Plumbing decisions made after the walls are closed up cost more, every single time — in money, in delays, and in patched-up finishes that never quite match. Here's what to lock down before your renovation or new build in George or the Garden Route gets underway.

Before builders start

  • Finalise fixture positions— where exactly each basin, shower, bath, and toilet will sit. Moving a fixture 300mm after first-fix plumbing is done means re-routing pipework, not just re-tiling.
  • Confirm water pressure requirementsfor any new fixtures — rain showers and certain bath fillers need higher flow rates than standard fittings, which can affect pipe sizing.
  • Decide on gas now, not later— if there's any chance you'll want a gas hob or gas geyser, route the gas line during first-fix. Retrofitting gas into a finished renovation is significantly more disruptive.
  • Plan for future access— inspection points for key valves and unions should be planned into the design, not forgotten until something needs fixing behind a finished wall.

First-fix vs. second-fix: know the difference

First-fix plumbing happens before walls, floors, and ceilings are closed up — this is when supply and drainage pipework gets routed. Second-fix happens after finishes are in place — taps, toilets, basins, and geysers get connected. Once first-fix is signed off and the walls close, changes become demolition, not adjustment. This is the point in a renovation where an experienced plumber earns their fee, catching issues before they're sealed behind tiling or plasterboard.

For older Garden Route homes specifically

If you're renovating an older property in George Central, Blanco, or similar established suburbs, budget time to properly assess existing pipework before finalising your renovation plan. Older galvanised steel supply lines are frequently found to be in worse condition than expected once opened up, and it's far better to know this before finishes are chosen than after.

Questions to ask your plumber before work starts

  1. Will the existing pipework be reused, or fully replaced?
  2. Is the current water pressure adequate for the new fixtures planned?
  3. Does the renovation trigger any compliance requirements (gas, drainage) that need certification?
  4. What's the sign-off process between first-fix and second-fix, and who inspects it?
The best time to make a plumbing decision is before the trade that depends on it starts. The second-best time is before it's tiled over. There isn't a third.
