Thursday Pools Review (2026): Fiberglass Pool Cost by Size

8.3/ 10

By the Renology editorial team · Reviewed by Dror Gigi, Co-Founder · Facts checked

Best for the clearest public cost guide, by pool size

Thursday Pools makes fiberglass pools at a single plant in Fortville, Indiana, and sells only through independent builders. It publishes the most detailed cost guide we found, updated in September 2026: most homeowners spend about $65,000 to $90,000 on a mid-size pool with standard decking. Thursday has also built most River Pools-brand shells since a 2015 joint venture, and bought River's manufacturing outright in 2021.

Thursday Pools cost, by size

Thursday's guide puts a fully installed fiberglass pool between $45,000 and $100,000 or more. By size: small pools under 26 ft run about $45,000 to $75,000, medium pools of 27 to 34 ft about $75,000 to $110,000, and large pools over 35 ft about $110,000 to $150,000 and up.

By scope, a basic install runs about $55,000 to $80,000 and a turnkey project about $65,000 to $100,000 or more. Thursday says most homeowners spend roughly $65,000 to $90,000 for a mid-size pool with standard decking and basic equipment.

Warranty

Thursday advertises a 35-year structural warranty and a 15-year surface warranty. Its website wording mixes "35-year" and "lifetime" in the same sentence, so read the written warranty: the River-brand version that Thursday issues says 35 years from installation and is one-time transferable.

Thursday Pools and River Pools

Thursday and River Pools formed a 50/50 manufacturing joint venture in December 2015, and Thursday built most River shells from then on. In 2021 Thursday acquired River's manufacturing and national dealer network outright. River Pools in Virginia remains an independent installation company.

Models and availability

Thursday lists about 44 designs, including spas, wet decks and wading pools. Plunge models such as The Nook measure 8 ft 4 in by 16 ft. The largest, Goliath, is 16 by 41 ft, and the deepest, Monolith, reaches 8 ft 6 in.

Thursday does not sell to homeowners or install pools itself. We did not confirm a California builder, so West Coast buyers should ask the company for the nearest one and price the freight from Indiana.

What we like, and what is worth knowing

What we like

  • A detailed, recently updated cost guide by size and scope
  • A 35-year structural warranty
  • The deepest model we found (8 ft 6 in)
  • A clean BBB record

Worth knowing

  • No California dealer confirmed
  • Only one plant, in Indiana, so freight to the West adds up

Choose Thursday Pools if

  • You want clear cost ranges before you talk to anyone
  • You want a deep diving-style pool
  • There is a Thursday builder near you

Look elsewhere if

  • You are on the West Coast and want a nearby factory (Latham or San Juan)
  • You want a lifetime structural warranty (Leisure or Barrier Reef)

Get your yard checked by a local pool contractor

Crane access, excavation, the pad, electrical, fencing and permits decide most of the gap between a pool price and a finished backyard. In Southern California, the Bay Area and Greater Seattle, we can introduce you to 2 to 3 licensed pool contractors who can walk your yard and price that part.
