20. Set up a spa
Create a relaxation spa-like space with the addition of a hot tub. A four-seat tub will suit the average family. You can buy a basic inflatable hot tub for between £300-£500, with off-the- peg designs in fibreglass or acrylic costing between £2,500-£4,000, depending on design.
Extras, such as lighting, audio and water features, will cost more and you’ll need to factor-in installation and running costs. Custom-built, wood-fired tubs don’t need electricity, as the heater is fuelled by dry wood – expect to pay upwards of £3,500.
Top tip: Find a solid, level base, such as concrete, which may need reinforcing to handle the weight of a full tub. You’ll need access to water and electricity and the surrounding area should be clean so dirt won’t get in.
