4-Person Hot Tub Dimensions and Gallons for a Small Backyard

How big is a 4-person hot tub and how many gallons does it hold?

Cove 4 measures 78.7 × 78.7 × 37.8 inches and holds 277 gallons. That makes the shell close to a 6.6-foot square before allowing for the open cover, steps and future equipment service.

Draw the full working footprint on the ground with tape. Open nearby gates, doors and storage areas to make sure the planned spa does not interrupt normal backyard use.

• Confirm the narrowest gate and every turn in the delivery route
• Keep the equipment side accessible for service
• Plan where an open cover and cover lifter will sit
• Check overhead branches, roof edges and drainage

Four seats do not mean four identical seats

Cove 4 uses two loungers and two upright seats. That works well for a couple that wants full-body reclined positions while keeping space for two guests. A family that prefers conversation may favor more upright seating instead.

• Loungers use more of the shell than upright seats
• Compare who will use the spa most often—not only maximum guest count
• Ask for the internal layout and dimensions before ordering

Prepare the site before delivery

A filled acrylic spa is a substantial load. A qualified local professional should confirm that the proposed foundation or deck is level and structurally suitable. A licensed electrician should confirm the final circuit, disconnect and local requirements.

Send the model, ZIP code, access width and site photos when requesting a quote. Those details help separate the spa price from freight, lifting and local site work.
