Designing the Water System Layout

The piping architecture follows different logic based on room size and intended use. A rational layout reduces pipe runs and facilitates future maintenance. For a complete selection of fixtures and fittings, explore our home improvement collection.

Service Bathroom System

In small rooms, often without a shower, the configuration should be essential. It's strategic to include spare connections and pre-installed drains for a washing machine, making the space versatile without future structural work. Consider adding a compact bathroom vanity to maximize storage.

Bathroom with Shower

In medium-sized spaces, the most effective solution involves aligning fixtures on a single wall. This technical choice optimizes the plumbing system by simplifying pipe runs and minimizing interference with the floor area. Complete the look with mirrors and lighting from our curated selections.

Master Bathroom

In larger rooms, distribution can break free from perimeter walls. Fixtures can be installed in the center of the space, creating a luxurious layout. For a cohesive design, browse our sofas and rugs to furnish adjacent areas.

Regulations and Minimum Bathroom Dimensions

Building codes specify minimum dimensions and clearances around fixtures. Ensure at least 60 cm in front of a toilet and 70 cm in front of a sink. For detailed planning, our outdoor patio furniture collection can inspire complementary living spaces.

Expert Tips

• Always install shut-off valves for each fixture for easy maintenance.
• Use flexible hoses for final connections to reduce stress on pipes.
• Insulate hot water pipes to minimize heat loss and energy costs.
• Consider a storage bench for extra bathroom organization.
