Hot Tub Installation Costs in the UK

Purchasing a hot tub involves more than the sticker price; you also need to prepare your garden, install electrics and budget for delivery.

Base preparation

• Concrete slab or reinforced decking: A hot tub weighing 2–3 tonnes when filled needs a level, solid base; pouring a concrete pad or building reinforced decking costs £500–£1,500 depending on size and access.
• Surface levelling and groundworks: Clearing turf, laying sub‑base and ensuring drainage can add £200–£500.

Electrical installation

• Dedicated power supply: Installing an RCD‑protected 32‑amp supply with armoured cable typically costs £600–£1,200.
• Trenching and cabling: Digging trenches and burying cable from your consumer unit to the tub adds labour; expect £300–£600.

Hot tub purchase price

High‑quality hot tubs cost anywhere from £5,000 to £25,000 depending on size, features and brand. Entry‑level models start around £3,000, while premium acrylic spas with multiple pumps and jets can exceed £10,000.

Delivery and positioning

• Standard delivery: A two‑person delivery with dolly or sled costs about £500.
• Specialist access: Crane or hi‑ab hire for tight spaces can cost £800–£1,500.

Ongoing running costs

An energy‑efficient hot tub costs around £1–£1.30 per day to run, plus chemicals (£20 per month) and service/repairs (£150–£500 per year). Factor these into your budget to avoid surprises.

Summary

Installing a hot tub requires planning and investment beyond the purchase price. Budget for a stable base, electrical work, delivery and running costs to enjoy a stress‑free soak.
