Products may include portable inflatable models, rigid-shell tubs and larger swim spas, with options such as built-in seating, lighting, jets, covers and steps. Some suppliers also provide water-care chemicals, filters and replacement parts. Services can include advice on choosing a suitable model, delivery, site preparation, installation and guidance on filling, heating and treating the water. Hire businesses may provide short-term rentals for events or holidays, including delivery and collection. Maintenance work commonly covers cleaning, water testing, filter replacement, repairs to pumps and heaters, and winterising or recommissioning a tub. Customers may also be able to arrange servicing contracts and buy accessories such as lifters, covers and cleaning equipment.
