N5 is a 2026 national bathroom renovation cost guide, N6 a national renovation cost guide on mid-2024 to early-2025 data, N7 a 2026 national bathroom retiling guide. The three are not combined.
The spread between guides comes from scope: a retile keeps the bath, basin and toilet where they are, while a full renovation replaces fittings, pipes and sometimes the layout.
Johannesburg Rules for a Bathroom Remodel
- Same layout. The City's building-plans page says replastering needs no permission, because no walls move and the drainage system is untouched. The City gives redecorating and replastering as examples; confirm the approval requirements for the proposed bathroom work with Building Control.
- Moving walls or drainage. The same page says any alteration that changes the structure of an existing building must be approved by the City. Moving a toilet changes the drainage.
- Removing an internal wall. The City's plan-submission checklist lists demolishing an internal wall that does not affect structural safety as minor building work, still with a motivation letter to the Building Control Officer.
- Plumbing. Section 37 of the Water Services By-law, 2004 reserves installation work beyond repairing or replacing an existing pipe or fitting for a qualified plumber. Section 39 requires water installations to comply with SABS Code 0252 Part 1.
Ask the quote to state which work changes the layout, which approvals the City requires for it, and which qualified plumber does the plumbing.
Shower Waterproofing and Walk-In Showers
A bathroom leak into a neighbouring room often starts in the shower. Grout lets water through; the membrane underneath stops it.
- The floor is screeded to fall to the drain.
- A liquid or sheet membrane is applied to the floor and carried up the walls, with reinforcing tape in the corners and around the drain.
- The membrane cures, then it is checked before tiles go on.
- Tiles, grout and silicone finish the surface.
N7 prices waterproofing to wet areas at R150 to R300 per m². As arithmetic, a 6 m² shower floor and wall area comes to R900 to R1,800. Tiling detail is on tilers in Johannesburg; an existing shower that already leaks is traced under leak detection in Johannesburg.
Toilet Installation, Vanities and Fittings
- Toilets: close-coupled, back-to-wall or wall-hung with a concealed cistern. A wall-hung toilet needs a frame in the wall, so it is planned before tiling.
- Vanities and basins: floating or floor-standing, with the waste and supply positions set before the wall is tiled.
- Baths: built-in or freestanding; a freestanding bath needs a floor waste in the right place.
- Hot water: an extra shower or a bigger bath may outgrow the geyser. See geyser installation in Johannesburg.
The Order of Work in a Bathroom Renovation
- Strip-out of fittings, tiles and damaged plaster; rubble removed.
- Plumbing and drainage first fix, pressure-tested before it is covered.
- Plaster and screed repairs, then waterproofing in wet areas.
- Wall and floor tiling.
- Fittings, silicone, ceiling paint or a PVC ceiling for the damp room.
Section 57 of the Consumer Protection Act makes the service provider answerable for new parts installed during a repair, and the labour to install them, for three months. To have a bathroom measured, request a quote.
Johannesburg Home Repairs: Questions Homeowners Ask
How much does a bathroom renovation cost in Johannesburg?
A 2026 national guide puts a bathroom renovation at R19,000 to R69,000, with an average of R44,000. Another national guide, on mid-2024 to early-2025 data, puts a budget bathroom at R30,000 to R60,000 and a mid-range one at R60,000 to R120,000.
Do I need building plans to renovate a bathroom in Johannesburg?
Structural alterations require City approval; confirm the paperwork for the specific bathroom layout and drainage changes with Building Control. The City of Johannesburg's building-plans page says replastering needs no permission because no walls move and drainage is untouched, while any alteration that changes the structure needs approval.
Can I move the toilet or shower?
Yes, with the right plumber and paperwork. Section 37 of the City's Water Services By-law reserves new installation work beyond repair or replacement of an existing pipe or fitting for a qualified plumber. Ask Building Control which approvals the proposed drainage and structural changes require.
What determines the sequence of a bathroom renovation?
The scope, drainage changes and waterproofing curing requirements determine the sequence. Plumbing and drainage are checked before covering, and waterproofing cures before tiling. Ask the written quote to state the planned sequence and duration.
Is shower waterproofing really necessary under tiles?
Yes. Tiles and grout are not waterproof; the membrane under them is. A 2026 national tiling guide prices waterproofing to wet areas at R150 to R300 per m² and notes the membrane cannot be fixed later without stripping the tiles.
Can a walk-in shower be built in an existing bathroom?
Usually. A walk-in shower needs a floor that falls to the drain, a membrane carried up the walls, and enough space for the glass panel to keep water in. The site visit checks the floor build-up and the drain position.
