SeraPool Natural Cotto Porcelain Concealed Drain Grates
Sold by the Piece
Custom order: produced for your project and shipped direct from the factory. Lead time is confirmed with your quote.
SeraPool Natural Cotto Porcelain Concealed Drain Grates 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 Natural™ Outdoor & Pool Collection, where the pool interior, coping, grates and deck are specified as one porcelain system.
Cotto is a terracotta-red porcelain surface inspired by traditional cotto. Pool coping, grates and deck tile are produced separately, so slight tonal differences between them are normal for this natural look; blend pieces from several crates during installation.

Installation notes
- Order the grate width to match the finished gutter opening; grates rest on the gutter ledges and lift out for cleaning the gutter.
- Do not cut the ABS plastic parts underneath; plan runs in full grate lengths.
