Choosing the Right Size

The minimum comfortable showering space is 760×760mm, though 900×900mm is far more comfortable. Consider:

• Available floor space: Measure the recess or corner area
• Door clearance: Allow 600mm+ in front for door swing or entry
• Bathroom layout: Keep 200mm between enclosure and WC/basin
• Accessibility: 1200×1200mm minimum for wheelchair access

Enclosure Types

• Quadrant: Fits in a corner, curved front saves space — ideal for small bathrooms
• Sliding door: No door swing into the room — good for tight spaces
• Pivot/hinged door: Full opening but needs clearance space
• Bi-fold door: Compact folding action, minimal clearance needed
• Walk-in/wetroom: No door, uses a fixed screen panel

Tray Depth

Low-profile trays (25–40mm) sit almost flush with the floor and look modern. Standard trays (40–90mm) are easier to install without floor modifications. High trays (90–150mm) are rarely used in new installations.

Building Regulations

Shower installations must comply with Building Regulations Part G (sanitation) and Part P (electrics if applicable). Waterproofing is essential — use appropriate tanking and backer boards in wet zones.
