How can we effectively waterproof around our fixtures in our 1926 bungalow bathroom remodel without using the large collars typically seen?

Hey!
We’re in the process of redoing the bathroom in our old bungalow from 1926 and we’re getting ready to waterproof it. We’ll be putting up cement board this weekend and we’re trying to figure out how to waterproof around the fixtures, like the diverter and hot/cold handles. We chose fixtures that don’t work with the big collars I usually see. Any advice on how to tackle this would be greatly appreciated!
Thanks a bunch!
They usually come with foam backing behind the plates. If not, just apply a line of Silicone
You might want to consider upgrading the valve to one with a single handle and pressure-balancing cartridge. A bit of silicone should do the trick, and it’s usually sufficient.
We decided to purchase this one because we liked the style and thought it was from a reputable brand. Is there a problem with this style or is a single-handle diverter just preferred? We’re redoing our master bathroom next and would love to learn for next time!
It’s your house, but I would suggest a pressure-balancing cartridge. This ensures that the temperature remains constant while someone is showering or kids are taking a bath. It’s actually in the building code. The brand is fine, I’m just thinking about safety and comfort.
Got it, thank you so much! We have a baby so we need to take that into consideration. If we had known beforehand, I might have chosen this one for us and a different one for the tub.
Hiring professionals ensures that projects are completed accurately and may offer more, and sometimes better, options.
I totally understand your preference for the style. The newer single handle styles actually come with a safety feature that reduces the hot water pressure when a toilet is flushed, so you won’t get scalded while showering. However, three-handle units lack this feature, so if the cold water pressure drops, you’ll only get hot water from the heater. I was just discussing this with my dad because there’s a three-handle unit in the bathroom at my parents’ house that used to be mine. It’s really difficult to shower when the washer is running.
Are you really going through a remodel just to install those inexpensive valves with a shower head from the 60s?
Once your tile is in place on the cement board, simply apply some butyl silicone around the tile and piping to seal any gaps. There’s no need to fill cavities in case repairs are needed down the line.
Thank you !
I installed a Kingston Brass shower control set and was pleasantly surprised by how sturdy and well-crafted they looked given the price. They’re made of solid brass. I sealed them with silicone caulk.
