A beautiful bathroom depends on what’s behind the tiles. Before you pick taps and tiles, make sure the plumbing plan is solid. This practical checklist, built around Algarve homes and water conditions, will help you avoid weak showers, slow drains, leaks and expensive rework.

1) Start with Pressure & Flow

• Measure static pressure and flow at key points (kitchen, main bathroom, top floor).
  
• Balance hot and cold supplies to suit modern mixers and thermostatic showers.
  
• If you’re dreaming of a large rainfall head, confirm you have the flow to feed it, or choose an efficient model designed for lower pressures.
  

2) Layout: Short Runs, Smart Routing

• Keep hot and cold runs as short and direct as possible to reduce heat loss and pressure drop.
  
• Avoid sharp bends that add friction; use sweep fittings and sensible pipe sizing.
  
• Plan isolation valves at each WC, basin, bath and shower for easier maintenance.
  

3) Waste Falls & Venting (Goodbye, Drain Odours)

• Correct gradients prevent standing water and soap scum build‑up.
  
• Use the right trap depth for showers (especially low‑profile channels) to resist odour backflow.
  
• Provide adequate venting/air admittance where appropriate to stop gurgling and siphoning.
  

4) The Right Shower System

• Thermostatic mixers keep temperatures stable and safe.
  
• Check cartridge compatibility with Algarve water conditions; some models tolerate scale better.
  
• Choose heads and handsets with easy‑clean nozzles to reduce limescale maintenance.
  

5) Pipework: Materials & Sizing

• PEX, multilayer or copper, each has pros. Match the material to your layout and finishes.
  
• Correct diameters matter: undersized feeds create pressure complaints at peak times.
  
• Install manifold or zoned layouts in larger renovations to balance performance and simplify servicing.
  

6) Waterproofing That Actually Works

• Treat showers and wetrooms as tanked areas, not just tiled spaces.
  
• Ensure continuous membranes behind tile backer boards, with careful sealing at corners and penetrations.
  
• Pressure‑test before tiling; fix first, finish after.
  

7) Hot Water: Capacity and Comfort

• Confirm your hot‑water source can deliver the flow and volume your new fixtures demand (long showers, deep baths).
  
• Consider recirculation on longer runs to reduce wait times and water waste.
  
• Protect heaters with limescale prevention (see Article 1) to maintain efficiency.
  

8) Fixtures that Save Water (and Still Feel Great)

• Dual‑flush WCs, aerated basin mixers and efficient shower heads reduce consumption without ruining the experience.
  
• Look for limescale‑resistant cartridges and nozzles to keep that “new bathroom” feel longer.
  

9) First‑Fix to Final‑Fix: Order Matters

1. Strip‑out and survey hidden pipework
   
2. First‑fix plumbing and pressure/flow tests
   
3. Waterproofing and flood test
   
4. Tiling and curing time
   
5. Second‑fix: fit mixers, WCs, basins, shower glass
   
6. Final pressure/leak tests and commissioning
   

10) Compliance & Best Practice

• Follow local plumbing standards for pipe sizing, backflow prevention and safe hot‑water temperatures.
  
• Include accessible shut‑offs and clear labelling for future maintenance.
