I suspect that it would take a long time to fill a tub with a kitchen faucet, but otherwise I'm not sure...

The current faucet doesn't look as big as my new kitchen one. I would be willing to deal with a longer filling time if i could get a sprayer. I just wonder if the supply lines are different sizes so a different faucet won't fit.

Supply lines are normally the same however the head of a pull down faucet is very small. Normally bathtub sprayers are meant to act as shower heads when needed not only for cleaning the tub so my suggestion will also be no.

When you are looking at faucets, the specifications state the flow rate in GPM (gallons per minute). Look at the stated flow rate on kitchen faucets and tub faucets. I looked at a Kohler kitchen sink faucet that said it had a flow rate of 1.5. The Kohler tub faucet that I chose randomly to compare to (Alteo) has a flow rate of 16 gpm. That is a huge difference and the reason why @acm said the fill time would be longer with a kitchen faucet. To fully understand the difference, look at how many gallons your tub holds and do the math.

" Can you install a Kitchen sink faucet with a pull down sprayer in place of a deck mount roman tub filler? "

No. Never mind the physical size - as has been stated, the flow rate of a kitchen faucet is ~ 1.5 -2 gallons per minute. The tub would be cold before you got it filled.

Ok I can see the difference GPM would make but still wonder why the water pressure or flow would be so different if the supply line pipes are nearly the same size.

I still wish I could find a tub faucet that had a good pull out sprayer and swiveled like a kitchen sink. Those separate shower sprayer for tub decks would require cutting another hole. One of the telephone showers for clawfoot tubs might fit but are bulky. So how do i get my ideas to a plumbing fixture manufacturer :-)?

Flow restrictors in kitchen faucets because of the nanny state dictating how much water can come out of your kitchen faucet. Senators have staff to stand at the sink & fill the pasta pot & the dog's water bucket so they are removed from the real world. And the reduced supply line to the faucet from the water pipe is usually smaller. A 3/8 faucet supply line connected to 1/2" water pipe is usual. Where as tub fillers connect directly to 1/2" water line...usual scenario.

With 3 trip to Lowe's and Home Depot, we have one leaky sink faucet replaced, a matching one to put on the other sink and a roman tub filler. I caved and just bought the only deck mount tub filler they had in stock. It is a Lowe's brand, Allen + Roth. Any one have experience with that brand for plumbing fixtures? The worst part was the old shut off valves had to be replaced, Hope those little shark bite hoses last a long time. they were easier than sweating a pipe to a new valve.

We got the bid on the install of tile for the jack hammered floor and retiling the tiny shower. And picked tile which leads to more debates like base boards.

I will be painting all the trim and doors bright white so should we just continue the base board we have been upgrading through the house or use the bullnose that matches the stone look porcelain tile? Probably will use the white wood since we have leftovers in garage. can't wait to have them start Feb 1.

Make sure you learn beforehand how they will WATERPROOF your shower. You might ask them to put it in writing and then come here to make sure it will be done properly.

Yes we will be checking the waterproofing. He said they use Kerdi boards and i saw Redguard on some of his in progress projects. He said will re do shower pan because he can only guarantee the work if he completely seals everything. His son was one of the best craftsmen in my art classes so I am hoping to see that he gets that from dad. I hoping to not be one of those a sad post of a picture of tile work gone wrong.

IMO how could we possibly answer with no context not one pic of what you are dealing with. IMO this idea would look silly and not function properly."he can only guarantee if he seals everything" Oh you have bigger issues the the pull down

Yes Patricia I have a Lot of bigger issues that would be boring to air here and dealing with them took priority over posting pictures. Here is what I have:

Notice old faucet, it was exactly the same size opening as my nice kitchen Pulldown. So it could have worked to have one here except hubby had tight fit working through access panel in his closet. Our son had to chisel off old corroded handles and you can see the lovely original chocolate cultured marble where the new escutcheons are smaller. we can't afford a new tub so I will repair my tub refinishing.

We have been graffitting our intials in our home projects for 40 years. This is the third one in this old house. I can't wait to change the cover from a carpet remanent to new tile. we can fix the mistakes of the 3 previous owners.

These are some inspiration photos of what i want:

As an architect and artist, we are obsessed with things lining up. That top shelf should line up with the pencil tile but we aren't adding that kind of border. We do like the cantilevered shelves.

Ice storm delayed everything by a week but we have paid for the large format Forum ivory porcelain tile for floors and shower walls with matching bullnose. It has matte texture and very subtle stone pattern. We got white porcelain penny size hex tiles for floor and may add them to back of the niche. They also come in a matching tiny herringbone, but I wonder if we should stay with the same pattern shape or add some color or sparkle there. I fell in love with some mother of pearl hex tiles that are totally out of budget. We are working on what sort of white stone for shower curb that would be repeated in niche shelves and framing door opening for new door. All of those issues depend on the measurements after our tile guy rebuilds shower pan and wall wall proofing.

So yes I am dealing with a lot of bigger issues of plumbing and construction, while planning the aesthetics. And then there are those darn financial issue......

I think your first problem is relying on Home Depot or Lowe's.

They are there to sell you something, not repair something.

Go to a proper Kitchen & Bath Business, where they stand behind their products.

Yes but I needed something I could grab off the shelf and have hubby and son install that night to stop the two new leaks caused by repairs they jackhammered to fix. My sink blew black gunk the first time after the pipe replacement then started dripping as the tub did. We got decent Moen fixtures for the sinks and the tub filler can be upgraded whenever we actually replace tub. I am not a fan of these new skinny free standing tubs so that will be for phase two of the re do. Just hope the allen+roth one works til then.

The professionals we have been working with are awesome. We are professional enough to know when we can save money with our DIY expertise and when it pays to hire a professional who guarantees his work. It is even better when we have those who go above and beyond.

Tearing the shower down to the studs, our tile contractor found old termite damage and replaced that stud which looks like previous owner's repairs had not. ( It had an extra stud reinforcing the damaged one. We had treated house so there were no active bugs.) That was just doing quality work to make the stall sturdy but our guys from Grace Tile Remodeling have added a few extra touches.

They noticed my husband is very tall so they extended the pipe for the shower head yesterday. Today I discovered they added one of those cute little toe niches for leg shaving in addition to the one we had in the bid. I may not know all the details on how they rebuild that shower pan but I can tell they have an eye for detail.

Dealing with the in house architect ( the guy who needs the taller shower) can be more complicated but we have settled on the simplicity of repeating the hex tile in the niches with white quartz shelves. The question for tomorrow is should the exterior framing around the door opening be the same white quartz as curb and shelves or this travertine I found for 10 cents a piece. (Can I find 94 good pieces in that dust bin?)

The long bullnose tile on the bottom is the tile for the shower walls and bathroom floors.

Hey there! I feel your pain when it comes to complex plumbing issues, I had a similar situation with a leaky faucet a while back. But I found a solution that worked great for me! I came across the experts at https://www.maida.com.au and they were able to install a kitchen sink faucet with a pull down sprayer in place of my old deck mount Roman tub filler. I was a little skeptical at first, but it turned out to be a game changer. The pull down sprayer is so much more convenient and practical than the sprayers I had seen with deck mount tub faucets. I hope this information is helpful for you. Good luck with finding a solution and a plumber that you can trust.

ZeemShahid thanks for validating my Idea. After My husband and son replaced the tub filler i compared the old pieces and figured the plumbing could have worked. It will be an idea if we ever replace tub or build that dream ranch house.

Updates on our re do:

They are finished with the shower rebuilding and the discount travertine looks great with our porcelain tile. Slow but good work. Next comes all my repainting, and Texas weather has slowed my stripping the doors. I also got discount cabinet hinges so i don't have to strip all of those painted over by previous owners. It does commit me to painting vanities bright white like the doors and baseboards. Debating on going all neutral on the walls or keeping my soft blue green paint.
