Bespoke craft & made-to-measure pricing
Slot-drain sinks in porcelain stoneware and sintered quartz, made to measure
Bespoke slot-drain sinks in large-format porcelain stoneware and sintered quartz, made in Warsaw to the exact size of your bathroom. Precise 45° mitres, a concealed drain, and an exact match to the wall tile or the counter.

Material
Porcelain stoneware and sintered quartz — materials without compromise
Continuity with the design
The basin can be made from the same sintered quartz or porcelain stoneware as the walls and the counter — one interior, with no foreign texture.
Durability of sintered quartz and porcelain stoneware
Full resistance to scratches, staining, cosmetics, hair dye, and household chemicals. Zero absorption, and no regular impregnation of the kind natural stone needs.
A light construction
Unlike a heavy block of granite or marble, a basin on a rigid core does not overload the wall and hangs safely on concealed steel brackets.
Making
Made without compromise on quality
Reinforced epoxy joints
We use a specialist two-component adhesive. The joints are fully resistant to water and household chemicals. They will not darken or break down over time.
The right fall, an envelope
The proven geometry of the base sends water and foam fully into the slot drain, so nothing sits in the corners.
Safe chamfers
Every visible corner is hand-finished at 45°. There are no sharp edges, and no risk of an accidental chip.
Care
With your time in mind
Porcelain stoneware and sintered quartz do not need complicated care. The surface is dense, so warm water and a soft microfibre cloth are enough for a perfect clean. The basin can be cleaned with ordinary mild gels and melamine sponges.
A detailed care card comes with every piece.
Made to order
Individual solutions for your project
We make the washbasin exactly to the size of your bathroom. Premium textures are available: concrete, marble, slate, and matte solid colours. We work from your drawings and welcome interior designers.
Three forms
Three slot-drain geometries
Each design is fabricated to your niche measurements. Explore three proven drainage geometries tailored to your layout.

01Infinity ramp
Single-plane continuous slope to a rear hairline slot
A continuous plane of porcelain stoneware slopes downward at a calibrated 2.5° gradient into an 8 mm rear slot. Water sheets effortlessly across the tile into a concealed catchment box without splashing, eliminating traditional drain grates.
- Suited for
- Powder rooms, guest suites, and entries paired with wall-mounted faucets
- Detail
- Vein-matched 45° mitred transitions bonded with color-matched epoxy

02Monolithic double trough
An expansive, continuous basin shared by two faucets
A wide-format vanity spanning 1400 mm to 2400 mm serving two wall-mounted or deck-mounted faucets. A single linear slot along the rear edge replaces the center joint and duplicate chrome hardware of two separate undermount bowls.
- Suited for
- Shared master bathrooms and hospitality interiors
- Detail
- Configurable with dual independent P-traps or a single central manifold to align with on-site plumbing rough-ins

03Deep mitred apron
A floating monolithic block with 45° waterfall edges
Creates the visual presence of a solid 150–250 mm stone block floating off the wall. The porcelain stoneware wraps continuously across precision 45° mitred joints with no visible tile trims or overlap seams.
- Suited for
- Spaces where base cabinetry is omitted
- Detail
- Reinforced internal chassis prepared for heavy-duty concealed steel wall brackets, with a recessed underside channel for LED accent lighting
