I used your option 3. The purist faucets for the sink and then for the tub I used the Purist faucets, diverter, handheld (which is basic for all their models) and the big gooseneck. I was told that using the smaller one would (a) take forever to fill tub and (b) probably not reach over the edge of the tub. As it turns out, the way it is mounted, the water just makes it over the side of the tub.

In my last msg second one is Pfister, and last two are Kraus. I usually look on faucet.com because they have a wide selection. I was playing off the square part of your faucet with that second choice, but I see what you mean about round stems. How about... This one is fun and unusual with curves and square... Curves: There are so many fun ones. Not much help am I? My honest opinion is the second one of the two you selected looks like a built in soap dispenser. Thus not my fav. There are too many other possibilities that won't encourage someone to push down on the top hoping for soap! ;) Good luck.

Flow rates are very different between kitchen faucets and roman tub faucets. The water in the tub would be cold by the time it filled if you used a kitchen faucet. It's fairly simple to drill another hole in an acrylic tub and replace your current faucet and rough in with a model that has a separate hand shower. If you have a cast iron model, the tub deck surround could be drilled for the faucet location instead of the tub itself.

Wow so much info coming in. YOU WANT HIGH FLOW TUB FILLER?? READ... HERE IT IS..... So much bad info above, even from the pros. Everyone just living with the poor performance of all the new stuff out there. I am a mechanical engineering technologist - I tested my old and new fillers. MY 1980s TUB FILLER... ( I refer to the complete faucet set with valve set as the FILLER) fills my old boring tub to the over flow in 4 minutes. My piping is 1/2" copper and my velocity** pressure is about 48 PSI at that point. I then measured with 5 gallon buckets the flow rate at 16 GPM.. Its been installed for 40 years and pipes all are in great shape- (I have since upgraded piping to PROPEX with a home run to each appliance and so cut up the pipe to have a look). I bought a new tub filler, one with those stupid braided hoses. IT WAS VERY DISSAPOINTING. Most tub fillers- especially the free standing are at only 1.8 GPM and 3.8 GPM unless you pay like $3K sand even then you might get 4 or 5. If it has hoses inside..its VERY LIKELY NOT THE ONE YOU ARE LOOKING FOR. those hose can be 3/8" only and have even tighter restrictions at the connections. It it says its 8 GPM you did well not bad but still less than 1/2 of what your old tub did. Most of todays TUB FILLERS.... are built to look great but do not even come close to meeting the task at hand. UNLESS you have a very small tub. 8 GPM would be OK in comparison but anything less is a JOKE. SO ... LOOK FOR units with OLD SCHOOL COPPER SWEAT MANIFOLD design. CHECK SPECIFIED FLOW RATE. Here is the one that fills like I expect it to its specified for 18 GPM --- add it is COMPLETE with the VALVE SET.. ********************* MOEN Adler Chrome 2-Handle Deck Mount Roman Bathtub Faucet (Valve Included) MFR#: 86998 They stopped making these I suspect because its so much CHEAPER to GO WITH THE FLOW and standardize on the easy to manuf.. braided contraptions. LOOK FOR HARD COPPER MANIFOLD/VALVE SET ** VELOCITY PRESSURE vs STATIC PRESSURE. The former is pressure measured in the flowing water. Static is what most ppl would think of as pressure. Static pressure will always be the same everywhere in your piping system. However, when the water is flowing, everything will take away pressure including restrictions, length of pipe and even roughness inside the pipes.
