Custom Pools & Spas

Scroll to explore

Every Signature pool begins as a blank sheet of paper. We design and build custom gunite pools and spas — from classic geometric designs to vanishing-edge pools overlooking Lake Keowee — along with full renovations that bring older pools up to today's standards.

Our approach

Every pool starts as a blank sheet of paper.

We design in 3D before the first stake goes in — shape, depth, finish, the way light hits the water at six in the evening. Gunite gives us total freedom; the discipline is knowing what to leave out.

Consultation

Your vision is our foundation.

Whether you arrive with a blank canvas or a finished set of architect's drawings, we start at your property — walking the site, talking through how you entertain, and sketching the first ideas on the spot. No proposal is written until the concept is right.

What we build

01

New construction

Gunite (shotcrete) construction gives us complete freedom of shape, depth and finish. Vanishing edges, knife edges, sun shelves, in-water loungers, swim-up bars and integrated spas are all designed in 3D before the first stake goes in.

New construction — Lakeside Modern, Clemson, SC
02

Custom spas

Raised spillover spas, in-pool spas and stand-alone gunite spas finished in glass tile, glazed ceramic or natural stone — each with its own heating, jets and lighting circuits so it runs independently of the pool.

Custom spas — The Courtyard, Greenville, SC
03

Water features

Sheer-descent walls, deck jets, bubblers, natural boulder waterfalls and grottos. Water features are designed for sound and sight lines from inside the house as much as from the pool deck.

Water features — Cascade Grotto, Spartanburg, SC
04

Renovations

We renovate and modernize older pools — including pools built by other companies: new plaster and tile, coping and decking, equipment, automation, LED lighting, and structural updates such as adding a spa, a sun shelf or a vanishing edge.
