Understanding Tap Hole Configurations: 0TH, 1TH, and 3TH
When selecting bathroom fixtures, understanding tap hole configurations is essential to ensure compatibility between your basin, bath, or countertop and your chosen tapware. The primary configurations are 0 tap hole (0TH), 1 tap hole (1TH), and 3 tap hole (3TH), each supporting different tapware setups that influence both functionality and design.
0 Tap Hole (0TH) Configuration
A 0TH configuration means the fixture has no pre-drilled tap holes. This setup is ideal for:
- Wall-Mounted Tapware – Taps are installed directly onto the wall above the basin or bath, creating a sleek and modern look.
- Countertop-Mounted Tapware – Taps are installed on the countertop or vanity surface, offering flexibility in positioning.
Advantages:
✔ Design Flexibility – Allows for custom tap placement to suit preferences and ergonomic considerations.
✔ Minimalist Aesthetics – Keeps the basin or bath surface clutter-free.
Considerations:
❌ Installation Complexity – May require additional plumbing work, especially for wall-mounted taps.
❌ Higher Installation Costs – Potentially more expensive due to custom setups.
Example Product:
👉 Fienza Reba Semi-Inset Basin (0TH) – Ideal for wall-mounted or countertop-mounted taps.
1 Tap Hole (1TH) Configuration
A 1TH configuration features a single pre-drilled hole, making it perfect for:
- Lever Mixers – Single-handle mixers that control both hot and cold water in one streamlined tap.
Advantages:
✔ Simple Installation – Requires minimal plumbing adjustments.
✔ Modern Design – A clean, contemporary look with a single, sleek tap.
Considerations:
❌ Limited to Single-Hole Taps – Not compatible with three-piece tap sets.
Example Product:
👉 Fienza Reba Left Bowl Wall Basin (1TH) – Designed for lever mixer taps.
3 Tap Hole (3TH) Configuration
A 3TH configuration includes three pre-drilled holes, suitable for:
- Three-Piece Tap Sets – Separate hot and cold taps with a central spout.
Advantages:
✔ Classic Look – Ideal for traditional or vintage bathroom aesthetics.
✔ Separate Temperature Control – Offers independent hot and cold water taps.
Considerations:
❌ Requires More Space – Needs enough room for all three components.
❌ More Complex Installation – Requires multiple plumbing connections.
Example Product:
👉 Caroma Concorde 500 Wall Basin (3TH) – Designed for three-piece tap sets.
