SeraPool Relax Anthracite Full-Body Porcelain Concealed Drain Grates & Corners are concealed (hidden) gutter grates: the drainage slots sit in the side gaps, so each grate reads as a solid porcelain band and the overflow gutter disappears into the deck. They are part of the SeraPool Relax™ Outdoor & Pool Collection, where the pool interior, coping, overflow pieces and drain grates are specified as one porcelain system.
Anthracite is a deep charcoal anthracite, full-body porcelain: the color and texture run through the whole body, so bullnose edges, cut edges and worn areas keep the same appearance as the surface. Its non-porous surface does not absorb water, resists stains and is easy to clean, and the full-body porcelain holds its color in sun, frost and pool chemistry.

Installation notes
- Order the grate width (10 in. or 12 in.) to match the finished gutter opening; grates rest on the gutter ledges and lift out for cleaning.
- Use 90° corners at square pool corners and 45° corners where the gutter turns at an angle, in the same width as the straight grates.
Matching Anthracite full-body system
Every piece below is made in the same Anthracite full-body porcelain, so coping, overflow edges and drain grates finish as one perimeter:
- Anthracite pool coping
- Anthracite slot overflow coping
- Anthracite slot overflow edge tile
- Anthracite drain grates & corners
