Tub-to-Shower Conversions in Jacksonville
Tub out, shower in: a new valve, a larger drain, a real pan or membrane, tile or panels, and safety glass. Hall baths and garden tubs across the First Coast.
The most common bathroom job around Jacksonville: a tub that nobody bathes in anymore becomes a shower that is easier to step into and easier to keep clean. In a hall bath the shower goes in the tub's footprint; in a primary bath the garden tub and the small shower beside it often become one larger shower.
It is a bigger job than it looks, because a shower is not a tub with the tub removed. The valve changes, the drain usually gets larger and moves, and the floor needs a pan or membrane that a tub never had.

What changes behind the wall
Most conversions include all of these:
- A new shower valve, pressure-balancing or thermostatic, with the hot limit set to 120°F
- A larger drain in the trade standard for showers, which usually means opening the floor or slab
- A pan: a liner under a mortar bed, a bonded membrane, or a solid-surface base, sloped to the drain
- Waterproofing on the walls up past the showerhead, then tile or solid panels
- A curb (the code sets its height) or a curbless entry where the floor allows it
- Tempered or laminated glass for the door or panel
Permit
Because the valve and the drain change, a conversion is plumbing work, and plumbing work is always permitted in Duval, St. Johns, Clay and Nassau, regardless of the 2026 small-job exemption. The pan is usually flood-tested and inspected before the tile goes on.
Keeping one tub in the house
If the house has two bathrooms, many owners convert one and keep a tub in the other for small children or for resale. It is worth deciding before the work starts.
