10 Bathroom Fundamentals

Advice from Kevin Denvir. 
  1. I’m old school Copper but some Flexible plastic pipework through Joists can make considerable savings.
  2. A good Isolation system is to have individual and Master shut off valves behind an access Panel.
  3. Concealing pipes involves chasing out walls & lifting floors for a genuine high-quality, clutter-free finish.
  4. Low-level shower trays may require raising floor levels & running wastes between or even below joists.
  5. Bad smells can be avoided by fitting anti-siphon valves in the waste pipe, or anti-siphon traps.
  6. Electric showers are a last resort if your existing Combi boiler lacks sufficient flow or pressure.
  7. Awkwardly situated bathrooms can use a pump with a macerator, similar to a waste disposal unit.
  8. Power showers require 50mm waste pipes not a standard 40mm size, due to the higher flow rate.
  9. For Circulating hot water consider a pump on circulating loop so Taps run hot instantly.
  10. Ensure a water pressure of 3-bar or more as required by most modern shower and tap mixers.
