Plumbing – How to replace shower / tub handles / spouts

bathtubplumbingshower

I recently bought a house with 20 year old fixtures 3 bathrooms including a shower, shower/tub, and roman tub. The shower knobs say Harden on them and the tub/shower knob has a separate tub/shower lever and the shower knob has a volume control lever. The Roman tub I'm not sure who makes it, but the knobs on the tub match the shower knob so perhaps they are also Harden. What I'm what I'm wondering is:

  • Can I replace the spouts/knobs without replacing the valves (all of the valves are in walls with no access)?
  • Assuming yes, how can I find knobs/spouts that will work with the existing valves? (I'm not sure if removing the tub spout requires turning off the water so I haven't wanted to do it yet).

Yes: Everything in your pictures falls into the realm of trim. If you remove the knobs, handles, and spouts, you will find valve and spout stubs. You should be able to remove all trim without shutting off the water.

Plumbing supply houses should be able to find compatible trim pieces.
