Bathroom sink designed to save counter space while staying simple to maintain. Owners fitting small cloakrooms will appreciate the compact oval shape and high-gloss porcelain finish of SmartSylva Undermount Bathroom Sink. Does the compact footprint and concealed overflow make it a sensible choice for a small bathroom?

⚡ At a Glance
  • Material & Finish: High-gloss porcelain glaze with low water absorption, scratch and stain resistant
  • Best for: Small bathrooms and cloakrooms where countertop space is limited
  • Not ideal for: Installations that need built-in faucet holes or a supplied drain assembly

Oval undermount porcelain sink with a hidden front overflow and rear drain position. Compact interior size suits smaller vanity units and requires a wall- or counter-mounted faucet.


Space-saving footprint – with compact oval undermount design

Undermount installation sits the basin beneath the countertop, using the provided mounting hardware so the rim does not add surface clutter. Interior dimensions are 14-3/4" by 11-1/2" with a 5-5/8" depth, leaving more usable counter area than many top-mounted bowls.

Fits neatly under smaller vanity tops to free up work surface and visual space. Ideal where a full-sized basin would overwhelm a cloakroom or compact bathroom.

Low-maintenance surface – with premium high-gloss porcelain glaze

The premium glaze produces a glossy finish with low water absorption and resistance to scratches and stains, helping debris and limescale wipe away more easily. The porcelain body resists everyday wear when cleaned with non-abrasive products.

Keeps a fresh, bright appearance with minimal effort and avoids frequent deep cleaning. Suitable for busy households that need a practical, hard-wearing basin.

Tidy plumbing and storage – thanks to rear drain position and hidden overflow

The drain is positioned towards the rear to align with a faucet spout and to maximise under-sink storage, while a concealed front overflow maintains the bowl’s clean lines. The standard 1-3/4" (45mm) drain opening is compatible with most pull-up and pop-up drains, though the drain assembly is not supplied.

Leaves more usable cupboard space beneath the basin and keeps the vanity area looking uncluttered. Requires purchasing a compatible drain assembly separately.
