Build the budget in layers
Separate the sauna package, delivery and unloading, groundworks and base, assembly, heater system, specialist work, permissions or advice, finishing and a suitable contingency.
Normalise every quote
A cheaper quote may simply omit more work. Ask every supplier to mark each budget line as included, excluded, optional or supplied by the customer.
Allow for ownership costs
Include energy or fuel, routine cleaning, external treatment where required, consumables, inspections and eventual replacement of wearing components.
Frequently asked questions
Why do garden-sauna quotes vary so much?
Size, material, heater system, delivery access, assembly scope, base work and specialist services can all differ. Compare an itemised all-in scope.
