Making Your Hot Tub Lighter: Is It Possible?
Unfortunately, you cannot make a hot tub lighter as its weight is primarily determined by its size and the materials it is made from. However, there are some strategies you can employ to make the hot tub easier to move or transport:
- Drain the Water: Draining the hot tub before moving it can significantly reduce its weight, making it easier to handle.
- Disassemble the Hot Tub: If possible, taking the hot tub apart can simplify transportation and reduce its overall weight.
- Use a Hot Tub Dolly: This special type of cart is designed to move hot tubs. It helps distribute the weight of the hot tub evenly, making it easier to maneuver.
- Enlist Help: Moving a hot tub is a challenging task, so it’s important to have at least two or three people to help you lift and carry it.
The Importance of Hot Tub Weight
Once you know the total weight of the tub, you can then divide it by the size of the tub in square meters (or feet) to get a number in kilograms (or pounds) per square meter (or foot). This is the load that your surface must absolutely support. A structural engineer can help with your hot tub on deck or concrete pad designs to ensure they can withstand the full load.
If your deck space is not engineered to hold the weight of the tub water, it could collapse or cause timbers to sag. More people are injured or even killed by collapsing decks than most people realize. Therefore, it’s crucial to ensure your deck can safely support the maximum weight of your hot tub.
Factors Affecting Hot Tub Weight
Weight will vary depending on setup, piping, number of jets, number of motors, etc. Hot tub shells, due to their size, can affect the weight the most. Hot tub shells can come in a variety of materials, each having their own strengths and weaknesses. Acrylic hot tubs will be the heaviest, while plastic ones will be easier to maneuver.
- Acrylic: Acrylic is one of the most durable materials for a hot tub shell, but it is heavier than some other options and can cost more than materials like fiberglass, plastic, and vinyl.
- Wood: Wooden hot tubs are usually made from cedar, redwood, and other trees. They have a more natural, classic appearance but can’t be molded into smooth shapes for benches and may have higher energy costs.
- Vinyl: Vinyl shells are less expensive and easier to move, but they are not very durable and are prone to cracks and tears.
- Rotomolded Plastic: This type of plastic is lighter and more affordable than acrylic.
Where to Place Your Heavy Hot Tub
The closer the spa is to your back door, the more it will be used. If you own a house, many people opt for the patio. If you have the option of placing the hot tub a bit further from the door, consider whether you would be using the hot tub during winter. Your deck is often the best option, but most older decks will need to be reinforced.
If you live in an apartment, avoid placing your hot tub on the balcony due to potential leaks. Instead, consider renting out a garage space at your complex. However, the safest bet would be to consult a licensed structural engineer to make the decision for you.
