Swapping a tub for a shower on the same drain is one of the cheaper bathroom changes. What moves the price, and when the job stops being simple.

Swapping a tub for a shower on the same drain is one of the better-value changes in a bathroom, because the layout does not move and only part of the room is disturbed.

- Keeping the **drain in place** is what keeps this job contained.
- Price moves with **which route** you take: a liner system over the surround, or a rebuild.
- It stops being simple when the **substrate is damaged** or the entry must be **curbless**.
- In a one-bathroom house, removing the only tub is worth a conversation with an agent first.

## Why it is usually contained

The tub comes out, the wall surface is dealt with, and a shower goes in where the tub was, using the existing drain position. No new plumbing runs, no floor opened, and the rest of the bathroom stays intact. Labour is the bulk of it — which is why the number varies by market, and why our estimator adjusts the labour share using state wage data from the [Bureau of Labor Statistics](https://www.bls.gov/oes/tables.htm) for trades including [plumbers](https://www.bls.gov/oes/current/oes472152.htm).

## What moves the price

**Which route.** A liner or wall system fitted over the existing surround is faster and usually cheaper to install. A conventional rebuild removes the surround and redoes the waterproofing. Both are covered in [walk-in shower cost](https://bathbudget.com/tub-to-shower/walk-in-shower-cost).

**The door.** A framed sliding door and a frameless glass panel are different money.

**The base.** A moulded acrylic base is the volume option; a tiled base is more work and more cost.

**Accessibility.** Grab-bar blocking, a bench, a comfort-height fixture and a curbless entry each add cost, and the curbless entry usually means altering the floor.

**Ask what happens if the substrate is wet**
The single question that separates a simple conversion from an expensive one is what is behind the tub. Agree in writing what happens if it is damaged, before anyone starts — the [FTC's advice](https://consumer.ftc.gov/articles/how-avoid-home-improvement-scam) to get scope in writing exists precisely for this moment.

## Bottom line

If the drain stays and the wall behind is sound, this is a contained job with a fair price. Get both routes quoted rather than one, and ask each what their process is if they find water damage.

## Common questions

### Is a tub-to-shower conversion expensive?

It is one of the cheaper meaningful bathroom changes when the drain stays put, because the layout does not change and only part of the room is touched.

### Does the drain have to move?

Usually not. A shower can often use the tub's existing drain position, which is what keeps the job contained.

### When does it stop being simple?

When the substrate behind the tub is damaged, when the floor needs altering for a curbless entry, or when the layout changes.

### Will removing the only tub hurt resale?

Ask a local agent. In a one-bathroom house it is a real consideration; in a house with another tub it usually is not.
