Shower and tub plumbing covers replacing a bathtub, converting a tub to a walk-in shower, installing a new shower valve and drain, and repairing leaking valves and drains. In Lakewood's 1950s slab homes, tub drains run into the slab, so drain location and condition are key planning points for a conversion.
Tub replacement
Replacing a tub in the same spot means removing the old tub (cast-iron tubs are heavy and often have to be broken up), checking the drain and overflow, installing the new tub and connecting a new drain and overflow assembly. The wall tile or surround usually has to be removed at least partly.

Tub-to-shower conversions
Converting to a walk-in shower usually needs a larger drain (commonly 2-inch rather than a tub's 1.5-inch), a properly sloped shower pan or base, waterproofing and a new valve set at shower height. On a slab, upsizing or moving the drain may mean cutting concrete. The City of Lakewood lists bathroom upgrades and plumbing work among projects that often need permits, per its home improvements guide.

Modern pressure-balancing or thermostatic valves protect against sudden temperature swings when another fixture is used. If your valve is old, leaks behind the wall, or trim parts are no longer available, replacing it during a remodel is sensible. See fixture installation for trim-only swaps.
Drains and leaks
Slow tub and shower drains are usually hair and soap, so see drain cleaning. Leaks below the tub or shower can come from the drain, overflow, valve or supply piping. In slab homes these leaks may show up as damp flooring in the next room. See leak detection.
Planning tips
Pick fixtures before rough-in so the valve and drain are placed correctly, plan for waterproofing, and ask who handles tile and drywall. The city's water-resistant gypsum and shower area handout on its permits and forms page shows what inspectors look for in shower walls.
