Fiberglass Spas

8 fiberglass spas.Soak the day away.

A Tallman fiberglass spa turns a pool deck into something closer to a resort. Pick a spillover model and the water rolls quietly into your pool all afternoon — pick a non-spillover and you've got a stand-alone soak that drops in almost anywhere. Either way, every shell is fiberglass, finished in Diamond Tech color, and built to keep its looks long after the acrylic hot tubs have faded.

Spill-Over Models

Water that flows from spa to pool.

A spillover wall lets warm spa water roll into the pool, keeping the air gently humid and the soundtrack constant. These five shells are designed to mate directly with our fiberglass pool models — plumbed, heated, and finished as one continuous build.

Spillover · Round

6' Round Spillover Spa

Footprint: 6' x 6'
Depth: 35"
Pairs With: Cancun

Our most compact spillover, the 6' Round is a tidy footprint with an outsized impact. Warm water laps over a rounded crest into the pool below, and the gentle hush it produces becomes the soundtrack of the backyard. Round seating keeps everyone within arm's reach — ideal for a tight conversation or a quiet soak before bed. Particularly well suited to smaller lots and to our Cancun and Key West shells, where it tucks in without crowding the deck.

Spillover · Octagon

7' Octagon Spillover Spa

Footprint: 7' x 7'
Depth: 35"
Pairs With: Monaco Bay

Eight clean facets give the 7' Octagon a sculptural presence — it reads less like a spa and more like a backyard centerpiece. The angled walls divide the bench into natural seats so the group spreads out instead of bunching, and the spillover wall sends a steady curtain of water into the pool. It's our most architectural spillover and pairs especially well with the Monaco Bay's geometry.

Spillover · Round

8' Round Spillover Spa

Footprint: 8' x 8'
Depth: 36"
Pairs With: Pacific

A genuinely social spa. The 8' Round opens up the seating without sacrificing the soft, inclusive feel of the smaller models — six adults can soak comfortably with elbow room to spare. The wider spillover edge produces a fuller sheet of water, which carries the sound farther across the patio. Looks at home alongside the broad lines of the Pacific or Rio Grande.

Spillover · Rectangle

9' x 7' Rectangle Spillover Spa

Footprint: 9' x 7'
Depth: 35"
Pairs With: Centennial

Built for rectangular pools and modern hardscape. The 9' x 7' Rectangle keeps every line parallel to the pool's coping, so the two read as a single integrated design rather than two separate water features. Long bench seating runs the interior, and the spillover lip is purposely wide for an even, mirror-flat overflow. Best alongside our Roman, Beach-Entry, and rectangular shells — particularly the Centennial and Kingsland.

Spillover · Kidney

10' x 7' Kidney Spillover Spa

Footprint: 10' x 7'
Depth: 33"
Pairs With: Abacos

The kidney's curved geometry softens everything around it — it's the spa we recommend when the backyard leans natural rather than formal. The inward arc cradles the seating, the spillover wraps around one shoulder of the shell, and the whole piece blends into stone, plantings, and freeform decking. A natural fit for our freeform and custom pools, and a near-perfect companion to the Abacos.

Non-Spillover Models

Standalone soaks, no pool required.

These three shells share the same fiberglass construction and Diamond Tech finishes as our spillover models — but they're self-contained. Sink one next to an existing pool, on a side patio, or on its own as the first phase of a larger backyard.

Non-Spillover · Octagon

7' Octagon Spa

Footprint: 7' x 7'
Depth: 35"
Pairs With: Standalone

Same eight-sided silhouette as the spillover version, configured to stand on its own. With no overflow edge to plumb back into a pool, the 7' Octagon is the easiest pick when the spa is going somewhere the pool isn't — a side patio, a screened porch, or a future-phase install where the pool gets added later. The geometric profile still works as a focal point on its own.

Non-Spillover · Rectangle

9' x 7' Rectangle Spa

Footprint: 9' x 7'
Depth: 35"
Pairs With: Standalone

Clean rectangular lines, generous bench seating, and zero hydraulic dependency on a pool. The 9' x 7' Rectangle is the choice for homeowners who want a properly sized soaking spa with the same fiberglass construction and Diamond Tech finish as our pool shells — but without the spillover plumbing. Drops into any deck layout, modern or traditional.

Non-Spillover · Kidney

10' x 7' Kidney Spa

Footprint: 10' x 7'
Depth: 35"
Pairs With: Standalone

An organic curve, a comfortable depth, and the freedom to sit anywhere on the property. The 10' x 7' Kidney is the standalone counterpart to our spillover kidney — it slips into garden beds and landscape pockets where a perfectly rectilinear spa would feel forced. Lower-maintenance than acrylic hot tubs, and built to outlast them.
