Delta Faucet Floor-Mount Freestanding Tub Filler Rough-In Valve for Delta Freestanding Tub Fillers R4700-FL, Chrome

This has to be the easiest and most nearly foolproof of the rough-ins for free-standing tub fillers. It is first class in all respects. You should be aware that this unit will work for Brizo AND Delta (verified with the manufacturer). If purchased as a Brizo it will cost you noticeably more. I bought the unit with the shutoff valves to make the installation a little quicker and easier but either variant will work. The result is a very solid faucet mount with no problems during installation. You will need some basic plumbing and carpentry skills to install this product but the instructions are reasonably good. I am not a contractor; just a homeowner that does most of his own repairs and upgrades around the house. I would buy another of these rough-ins for another project if needed.

The kit is not very easy to install and the instructions were not very clear. They referred to a stinger, which is simply a 2 x 10 or 2 x 12 cut to fit between the floor beams, but this didn’t make sense until I looked it up on YouTube. Once installed, it made the tub filler extremely easy to install and it’s very stable and I highly recommend this product but prep your plumber because it is a little unusual and if they don’t know the product, there is a video on YouTube that could help them out

Used this when we installed out new floor tub! Contractor said to purchase it since it was extremely well made and had water shut offs! He was right and the u it fit perfectly. Great job from Delta making this strong piece for water lines for the free standing tub!

This rough-in fills my tub extremely quickly. In fact, I’ve never had a tub fill so quickly. My contractor is very familiar with Delta so installation was straightforward for him. I have had no leaks with this product. I would recommend Delta bath products to anyone.

Great valve for delta products. Exactly as pictured. Also comes with a cover for protection while you build or remodel. It’s worth it.

Included instructions are basically just pictures but they are very clear and helpful. There's also video from Delta online. I haven't installed the finished tub filler yet, but the rough in was easy. I did have to solder connections to adapt to PEX, but it was easy enough. You have to do this on Delta shower rough-in valves also so I don't see taking a star off for that. I did take one star off because the mounting holes for the plate are not countersunk so you either need pan-head fasteners, or drill counter-sinks. I drilled counter-sinks shown in the pictures. If you install per the instructions, the top surface of the plate should be flush with the underside of the subfloor. If you leave the fasteners without countersinks, the subfloor won't lay flush. Alternatively you could recess the plate more, but when you tighten down the faucet nuts, you will be pulling the subfloor down, flexing it and risk breaking tiles.

This was what our experienced plumber requested and when it arrived I could see why. He said Delta is the brand he recommends and this rough-in valve with screwdriver stops is the one he uses. He, and the sales rep at a local plumbing store, both had the same answer… yes, to the mount WITH the stops. It comes with a “Guaranteed for life” warranty, and judging by the heft of this, it is the only one we’ll ever need. This is solid.

Great quality and got the job done- exactly what I needed

I bought this for the Delta Trinsic floor mount tub filler (which I am returning). This rough-in is necessary and not included with the faucet. There is a lower priced version that does not have stops. This is a solid piece of engineering, very well made - solid brass construction. For the difference in price vs the rough in without stops - this is well worth it when you factor in the years of potential use. If you ever have trouble with your tub filler, you can shut off the water to just the tub (vs your entire house).

Sooo expensive for what it is but that’s the only negative. Easy install and sturdy design
