Bathtub installation involves more than setting a tub in place — drain alignment, overflow connection, supply line routing, and proper leveling all matter for a leak-free installation. STL Plumbing Pros handles the plumbing side of bathtub installation: old tub removal, drain and supply connections, overflow setup, and leak testing. Looking for shower repair or faucet repair instead? We handle those too.
When to Replace Your Bathtub
Cracked or chipped tub surface that can't be refinished.
Persistent drain leaks at the tub shoe or overflow connection.
Bathroom remodel requiring new tub style or size.
Switching from tub/shower combo to standalone tub or walk-in shower.
Accessibility upgrade — replacing a standard tub with a walk-in model.
