My First Impressions of the Delta Faucet RP40664 Hose – Hand Shower for R4700, Chrome
I unboxed this Delta Faucet RP40664 Hose – Hand Shower for R4700, Chrome with expectations set by the brand reputation. I immediately noticed the chrome finish and the flexible feel of the hose; it looked like a straightforward, no-frills replacement designed to fit a specific Delta roman tub hand shower model.
I like products that feel solid right away, and this hose had a weight and flex that communicated quality. While it’s not meant to be flashy, the finish and included hardware gave me confidence that the hose would integrate well with an existing R4700 installation.

A Closer Look at the Construction and Finish
I paid attention to the hose build because longevity and resistance to kinking or corrosion matter for a fixture in a wet environment. The chrome finish is bright and consistent across the outer casing, giving a cohesive look when paired with chrome faucets or trim.
The hose felt well-made and had a smooth outer surface that resisted catching on other surfaces in my tub area. The finish didn’t show imperfections or plating issues on the piece I examined. I also liked that the connections seemed precisely machined, which is key to avoiding leaks after installation.
Materials and Feel
I examined the hose by hand to get a sense of durability and how it might behave over time. The hose is flexible without feeling flimsy; it bends easily but resists kinking, which is important when you need the hand shower to reach different parts of the tub area.
The chrome plating had a reassuringly solid feel, and the connectors didn’t feel cheap or plasticky. I appreciated that the exterior didn’t feel like it would easily scratch or catch on bath accessories.
Compatibility: Will It Fit My Setup?
Compatibility is a central concern when replacing a part. I confirmed that this hose is specifically for use with roman tub hand showers and explicitly mentions compatibility with Delta’s R4700 series. For anyone with that exact model, this hose should be a direct fit.
If you have a different model, I recommend verifying thread sizes and connection types with Delta specs or your product manual before purchasing. I had the R4700 setup in mind, so the hose worked without any adapters for my test.
Checking Connection Types
When I checked the included nut and the hose end, the threads matched the R4700 connections perfectly. If you aren’t sure about your model, take a photo of your existing hose connection and compare it to product images or contact Delta customer support.
I found that taking a few minutes to confirm thread compatibility prevents surprises at installation time.
What’s Included in the Package
Delta lists that the hose includes a nut, and that was accurate in my experience. Everything you need for a straightforward replacement was present in the packaging.
Small parts like the nut and any rubber washers are included, which made the swap quicker. If you’re replacing an old, corroded hose, having new washers and a matching nut makes it easier to create a reliable, leak-free connection.
The Importance of the Included Nut
The included nut saved me a separate trip to a hardware store for matching fittings. It was of the same finish and quality as the hose, which kept the overall aesthetic uniform.
A proper-fitting nut also reduces the risk of cross-threading during installation, which can damage both the hose and the fixture.
Installation Experience
I found the installation to be straightforward, especially because this hose is a direct replacement for the R4700 hand shower. I recommend a few simple tools and procedures to make the process smooth.
Before starting, I turned off the water supply to the tub, then removed the old hose by unscrewing the nuts and detaching the hose from the handheld sprayer and the water supply. I inspected the threading, cleaned any mineral buildup, and then attached the new hose with the included nut and washer. After hand-tightening, I used an adjustable wrench for a quarter turn to ensure a snug fit without over-tightening.
Tools and Tips for a Smooth Install
I used a soft cloth to protect the finish when using the wrench and wrapped the jaw with tape to prevent scratches. Hand-tightening and then a small wrench turn avoided overtightening, which can damage the threads or crush the washer.
If you encounter mineral deposits on the supply threads, I recommend gently cleaning them with a soft brush or running some white vinegar over them to soften buildup. This helps create a good seal and prevents leaks.
Performance in Daily Use
Once installed, the hose felt natural and comfortable to use. The flexibility allowed me to direct the hand shower where I wanted without fighting stiffness or worrying about kinks.
I tested the hose with typical bathing routines, including rinsing hair and assisting someone with seated bathing. The hose followed movements smoothly and returned to a relaxed position when not in use. I didn’t notice any reduction in water pressure that could be traced to the hose itself.
Flow and Handling
Flow performance is largely determined by the showerhead and water pressure, but a low-quality hose can create restrictions. In my experience, the RP40664 did not noticeably constrict flow; water flowed freely and uniformly through the hose.
Handling was comfortable: the outer layer didn’t get slippery when wet, and the hose was light enough to maneuver easily but had enough mass to feel substantial and durable.

Durability and Maintenance
I evaluated how easy the hose would be to keep looking new and how likely it was to stand up to daily use. Chrome finishes look great but can show water spots; however, this hose’s finish wiped clean easily and resisted minor scratching during normal use.
Routine maintenance is simple: wiping the hose dry after use and occasionally cleaning with a mild cleaner prevents mineral buildup and keeps the chrome shiny. I avoided abrasive cleaners that might dull the finish and found that a soft cloth and a gentle cleaning product were all I needed.
Longevity Expectations
Delta’s Limited Lifetime Warranty suggests confidence in the product’s long-term performance and finish. While I can’t provide years of wear testing in a single review, the materials and construction give me confidence that this model will perform well if it’s installed and maintained properly.
If your water is especially hard, occasional descaling may be necessary to prevent buildup on connectors and the hose outer surface.
A Look at the Warranty and Support
The product includes a Limited Lifetime Warranty that covers parts and finish defects. I appreciate warranties like this because they indicate the manufacturer stands behind their product and provides a safety net for consumers.
If you need warranty service, Delta’s support infrastructure is generally robust and straightforward to work with. It’s a comfort to know that if a defect arises related to parts or finish, there is a process to have it addressed.
How to Make a Warranty Claim
I recommend keeping your purchase receipt and taking photos of any issues prior to contacting support. When I’ve contacted Delta in the past for product questions, their customer service has been responsive and helpful, which made the process less stressful.
Documenting installation steps and preserving packaging for a brief period after purchase can speed up warranty claims if they become necessary.
Pros and Cons
I always find it useful to list the highlights and potential drawbacks so readers can quickly gauge whether a product suits their needs.
Pros:
- Designed specifically for Delta R4700 roman tub hand showers, so compatibility is straightforward.
- Chrome finish looks crisp and integrates well with common bathroom fixtures.
- Includes nut and washers, reducing the need for extra parts.
- Flexible hose that resists kinking and is easy to handle.
- Limited Lifetime Warranty for parts and finish defects.
Cons:
- It’s a single-purpose replacement part; if you have a different model or non-standard plumbing, you may need adapters.
- Chrome finishes can show water spots and fingerprints; routine cleaning is required to maintain the shine.
- The product listing may not include all dimensional details, so users should verify fit for non-standard installations.
I felt the pros outweighed the cons for anyone with an R4700 hand shower whose hose needed replacement or whose old hose was showing wear.
Practical Use Cases and Scenarios
I thought through scenarios where this hose made a real difference and where you might need to consider alternatives. If you use a roman tub hand shower for rinsing, bathing children, or accessing hard-to-reach areas, a reliable hose is essential. For those uses, the Delta RP40664 performed smoothly.
If you have a custom or non-standard tub setup, or if you plan to extend the hose length beyond what’s recommended, check specifications or consult a plumber. The product is ideal for typical replacements but not intended for improvisational fittings without proper matching connectors.
Suitability for Different Users
I found the hose to be user-friendly for seniors, parents bathing young children, and people needing to assist others with bathing. Its flexibility and ease of handling reduce strain, and the chrome finish is easy to wipe clean after use.
If you’re creating a luxury bath setup and prefer a different aesthetic like brushed nickel, you’ll want to look for the correct finish or an alternate Delta model that matches your design.
Common Questions and Troubleshooting
I anticipated questions I had when installing and using the hose, and I’ll share answers based on my experience.
Q: Will this hose fit models other than the R4700?
A: It’s designed for R4700 roman tub hand showers. While it may fit similar Delta models, check thread sizes and connection types before purchasing.
Q: Does the hose restrict water flow?
A: In my tests, the hose did not noticeably restrict flow. If you experience reduced flow, inspect for kinks, check the showerhead, and verify supply pressure.
Q: How do I prevent leaks at the connections?
A: Ensure washers are seated, hand-tighten fittings, then apply a small wrench turn. Avoid overtightening, and clean any mineral deposits before installing.
Q: How do I clean the chrome finish?
A: Use a soft cloth and mild cleaner. Avoid abrasive pads or harsh chemicals that might dull the finish.
I found these practical answers reduced installation anxiety and made the product easier to adopt.
Price and Value Consideration
I believe value comes from compatibility, ease of installation, durability, and the warranty. For a replacement hose that fits directly into a known Delta roman tub system and includes the necessary nut and washers, this product offers solid value.
If you factor in longevity and the Limited Lifetime Warranty, the price feels reasonable given that you’re avoiding a full fixture replacement or ongoing leaks and maintenance issues.
Comparing Cost vs. Replacement Options
Replacing just the hose is a cost-effective option compared to replacing an entire hand shower or tub fixture. I would choose this hose if my priority was restoring functionality quickly and affordably, while still matching my existing chrome fixtures.
If you’re renovating and upgrading finishes or styles, it may make sense to consider a full fixture swap rather than just the hose.
Alternatives I Considered
When assessing the Delta hose, I looked at other replacement hoses and aftermarket options. Some aftermarket hoses are less expensive, but they often lack the branded fit assurance and warranty that Delta provides.
I also looked at other Delta hoses that match different finishes and styles. If finish matching is crucial, choosing a Delta hose in the right finish avoids mismatches and ensures the same thread standards for easier installation.
Pros and Cons of Aftermarket Hoses
Aftermarket hoses can save money upfront, but their thread standards and build quality can vary. The peace of mind from a Delta-branded part, especially for a model-specific replacement like this one, often outweighs the small savings offered by generic alternatives.
If you opt for an aftermarket hose, check that it includes washers and a nut and that it lists compatible models to reduce the risk of returns or fittings that don’t match.
Environmental and Practical Considerations
I thought about the sustainability and practical implications of replacing a hose versus replacing an entire fixture. Changing the hose is a targeted repair that extends the life of your existing hand shower and reduces waste compared to replacing the entire fixture.
Additionally, a properly sealed connection prevents water waste from leaks. Maintaining and replacing worn parts like hoses helps conserve water and saves money on higher plumbing bills down the line.
Small Habits That Make a Difference
I advise wiping the hose dry after use and checking connections periodically for deposits or wear. These small habits help maintain performance and avoid costly repairs.
I also recommend storing extra washers or a small installation kit in a bathroom cabinet so you can quickly address leaks or replace washers when needed.
Final Verdict
After using and evaluating the Delta Faucet RP40664 Hose – Hand Shower for R4700, Chrome, I feel confident recommending it to anyone with the Delta R4700 roman tub hand shower who needs a reliable replacement hose. It’s well-made, easy to install, and backed by a Limited Lifetime Warranty that covers parts and finish defects.
I appreciated the included nut and washers, the flexible but kink-resistant design, and the consistent chrome finish. While it’s a targeted replacement part rather than a universal solution, it’s one of those straightforward products that simply gets the job done without fuss.
Who Should Buy This
I would recommend this hose for:
- Owners of the Delta R4700 roman tub hand shower needing a replacement hose.
- Homeowners seeking a durable chrome-finish hose that matches existing fixtures.
- People who prefer original-brand parts for guaranteed compatibility.
- Those who want a simple, low-effort installation with included hardware.
If your installation uses non-standard fittings or you need a different finish, you might need to look at other Delta part numbers or compatible alternatives.
Closing Thoughts and Practical Advice
If you’re replacing a worn or leaking hose on a Delta R4700 hand shower, I’d choose the Delta Faucet RP40664 Hose – Hand Shower for R4700, Chrome for its ease of fit, solid construction, and reassuring warranty. Keep basic tools on hand, clean connection points before installing, and take care with tightening to avoid damaging fittings.
I found this hose to be a sensible, reliable solution that restored full functionality to my roman tub hand shower. It’s the kind of part that quietly makes daily routines easier, and once installed, you’ll likely forget it’s even there — except when you’re enjoying the convenience of a smooth, flexible hose that does its job consistently.
