Can you put a shower where a tub used to be without major plumbing work?

Yes, you can usually install a shower where a tub used to be without major plumbing changes. Most tub-to-shower conversions use the existing plumbing connections since both fixtures require similar water supply and drain locations.

The existing hot and cold water lines that fed your tub can typically supply a new shower valve, and the drain location usually works well for a shower base. The main plumbing modification involves installing a new shower valve (mixing valve) to replace the old tub faucet, which is straightforward work for a licensed plumber. In Ottawa, this type of conversion typically costs between $3,000 - $8,000 depending on the shower style and finishes you choose.

Waterproofing is the critical step that many homeowners overlook. Even though you're using existing plumbing, the walls need proper waterproof membrane installation behind the new tile or shower surround. This prevents water damage that could cost thousands to repair later. The shower base also requires careful installation to ensure proper drainage and prevent leaks.

Ottawa building requirements may require permits if you're doing electrical work (like adding new lighting or ventilation) or making structural changes, but a basic tub-to-shower conversion often doesn't require permits. However, all plumbing work should be done by licensed professionals to ensure it meets Ontario Building Code standards and maintains your home insurance coverage.

The conversion typically takes 3-5 days and involves removing the old tub, installing the new shower base, waterproofing, tiling or installing shower walls, and connecting the new fixtures.
