A bath to shower conversion costs between R18,000 and R45,000 in South Africa in 2026. Most conversions land around R24,000 to R34,000.
It is one of the most requested small renovations we do, for three reasons: households stopped using the bath years ago, water is expensive and metered, and ageing-in-place has become a real consideration rather than a future one.
What drives the price
Whether the waste has to move — the big one
A bath waste sits at one end of the bath. A shower waste usually wants to be central, or at least positioned to suit the fall. If the existing waste can be reused, you save meaningfully. If it has to be relocated, the floor is opened up and the fall re-established, which adds R6,000 to R12,000.
On a ground floor with a screed over slab this is manageable. On a suspended timber floor, or a first-floor bathroom over a habitable room, it needs more care and costs more.
Tray versus tiled base
Dropping a tray into the bath footprint is the economical route at R18,000 to R26,000. Building a tiled, curbless walk-in runs R28,000 to R45,000 and looks considerably better.
The enclosure
A fixed glass panel is around R6,000 to R11,000. Frameless doors run to R14,000. A bath footprint is long, so a single fixed panel with a generous walk-in opening usually works well and avoids a door swinging into a small room.
The process
- Remove the bath and strip tiling in the surrounding area — usually a day.
- Assess the waste and supply. This is when you find out whether the pipework is sound. In older Cape Town homes, galvanised supply is common and often worth replacing while the wall is open.
- Re-route the waste if required, and set the fall.
- Screed to the drain.
- Waterproof and flood test. Non-negotiable, particularly where the bath previously contained water that a shower will now spray across a wider area.
- Tile floor and walls.
- Fit the enclosure, mixer and rose, then seal and snag.
Allow five to eight working days. It is quicker than a full bathroom because the toilet, basin and most of the room stay where they are.
Should you keep one bath in the house?
Yes, if you only have one bathroom. Estate agents are consistent on this: a home with no bath at all narrows the buyer pool, particularly families with small children. If you have two or more bathrooms, converting one is a straightforward improvement and rarely hurts resale.
If the bath is genuinely never used and you only have one bathroom, it is still your home to live in — just go in knowing it is a decision that may need explaining at sale.
The accessibility case
A curbless walk-in shower with a level entry, a fold-down seat and correctly positioned grab rails is far safer than climbing into a bath. If this is the reason for the conversion, plan it properly:
- Level entry, no step, with the fall doing the work
- Grab rails fixed into blocking behind the tile, not into plasterboard or hollow brick
- Slip-rated floor tile, verified rather than assumed
- A handheld rose on a rail in addition to any fixed head
- Enough clear width if a walking frame or wheelchair may be used
The rail blocking has to be installed before tiling. Retrofitting proper fixings afterwards means opening tile you have just paid for.
What you gain and what you lose
- Gain: usable floor space, easier and safer entry, lower water use, a more modern room
- Gain: easier cleaning, particularly with a wall-hung arrangement
- Lose: the bath, and some buyer appeal if it is the only one
- Watch: shower spray travels further than bath splash, so the waterproofed zone needs to be larger than the old bath area
If you are weighing it up, our team can look at the existing waste position and tell you quickly whether yours is a simple conversion or one that needs the floor opened — that single fact usually decides the budget. See our bathroom renovation services for how we quote it.
Frequently asked questions
How much does it cost to convert a bath into a shower?
R18,000 to R45,000 in South Africa, with most conversions at R24,000 to R34,000. Fitting a tray into the bath footprint is cheapest; building a tiled curbless walk-in with a relocated waste is the upper end.
How long does a bath to shower conversion take?
Five to eight working days. It is faster than a full bathroom renovation because the toilet, basin and most of the room are untouched.
Should I remove the only bath in my house?
Generally not, if resale matters. A home with no bath narrows the buyer pool, especially for families with young children. With two or more bathrooms, converting one is a common and sensible upgrade.
Does converting a bath to a shower save water?
Usually. A full bath uses roughly 150 to 200 litres. A shower with an efficient rose uses around 9 litres a minute, so a seven-minute shower is about 63 litres. Long showers with a high-flow rose can close that gap, so the saving depends on how it is used.
Do grab rails need special fixing?
Yes. They must be fixed into solid blocking or masonry behind the tile, installed before tiling begins. Rails fixed into plasterboard or hollow block will pull out under load, which defeats the purpose of fitting them.
