Bathroom Renovation Guide: Planning Your Project in Alberton & Johannesburg South

Small space, high stakes — bathroom renovations pack plumbing, electrical, waterproofing, and tiling into a tight footprint. Here's how to plan one that doesn't leak later.

Bathroom renovations are compact projects with a lot packed into a small space — plumbing, electrical, waterproofing, and tiling all need to work together correctly, or problems show up later as leaks and damage.

Why waterproofing is the step that matters most

Waterproofing is the single most important — and most often rushed — part of a bathroom renovation. Done properly, it prevents water damage to structures below and adjacent rooms for decades. Done poorly, it causes expensive, hard-to-trace leaks that can take years to show up. This isn't a step to cut corners on to save a small amount of budget.

Typical bathroom renovation sequence

1. Strip-out of old fittings, tiles, and fixtures.
2. Any plumbing relocation (moving a shower or toilet position).
3. Waterproofing — applied and properly cured before any tiling begins.
4. Tiling — floor first, then walls.
5. Fitting installation — toilet, basin, shower/bath fixtures.
6. Final electrical (extractor fan, lighting) and finishing touches.

Budget considerations specific to bathrooms

• Moving plumbing points (relocating a toilet or shower) adds cost — keeping the existing layout is the biggest single way to control budget.
• Waterproofing should never be treated as optional or skipped to save cost.
• Tile choice affects both material cost and labour time (large-format tiles vs mosaic, for example).
• Ventilation (extractor fan) is worth budgeting for even if not currently present — it protects the renovation you just paid for.

Common bathroom renovation mistakes

The most common issues we get called out to fix later are inadequate waterproofing, poor slope-to-drain on shower floors causing pooling water, and ventilation that was skipped to save a small amount upfront. All three are far cheaper to do right the first time than to fix afterward.

Toilet and fixture problems worth knowing about
