Walk-in tub installation for Knoxville homes

Hot Water Capacity

A deep walk-in tub can use most or all of a standard tank in one fill. We check the water heater size and recovery before you choose a tub, and recommend a larger tank, a tankless unit or a model with an inline heater if the household's current heater would leave the bath lukewarm. Getting this wrong is the most common complaint about walk-in tubs, and it is easy to prevent. We size the heater to the tub's gallons, not the brochure's fill time.

Fast-Drain Plumbing

Some walk-in tubs offer a fast-drain option with a larger drain or a pump. The house drain has to keep up: a fast-draining tub on an old, partly blocked line just backs up. We check the drain line beyond the trap, clean or replace it if needed, and connect the tub with the right trap and venting for its drain rate. We also check that the tub's drain outlet lines up with the existing floor drain, so the connection does not need an awkward offset that slows it down.

Jets, Heaters and Electrical

Hydrotherapy jets, air jets and inline heaters run on electricity and usually need a dedicated GFCI-protected circuit near the tub. We plan the plumbing around where that circuit and the tub's access panel will be, coordinate with an electrician for the wiring, and make sure the pump and heater can be reached for service later. Heated models keep the water warm while it fills, which helps with deep tubs, but the heater needs its own access panel and clearance. We make sure the panel faces an open side of the tub rather than a wall, so the next repair does not mean pulling the tub out.
