I've got a house remodel in the works that involves a spruce-up of two bathrooms and a kitchen. Involved are three faucet replacements. Two are straightforward. The bathtub has a faucet unlike anything I've encountered before. The house is 100 years old but I imagine this bathroom is 40-60 years old. The faucet is mounted directly to (through) the tub. The clearance above the overflow is very tight. I took some measurements and sketched this up. One KEY detail. Due to a closet I have full access to the supply pipes behind the tub. What I'd really like to do is find something that aligns with this hole pattern and run a shower feed up behind the wall to a "regular" showerhead. Am I going to have any luck finding this type of faucet??
