Thinking about Purchasing an AlumiTub? Here's What You Need to Know

The right AlumiTub comes down to three things: how often you plan to use it, what your property allows, and what kind of experience you are looking for. All three models share the same core construction. What changes is the heating system, and that choice shapes everything from daily routine to running costs to where the tub can go.

This guide walks through the key decisions so you can arrive at the right choice with confidence.

Start with how you plan to use it

The single most useful question to answer before choosing a model is how often the tub will realistically be used.

If the tub is destined for a weekend cabin or a seasonal retreat, the pattern of use is intermittent and intentional. You arrive, you light the fire, you soak. The preparation is part of the ritual. A wood fired hot tub model fits this kind of use naturally, and the fact that it requires no infrastructure means it can go to the kinds of places a cabin or retreat tends to be.

If the tub is going into a primary residence and you plan to soak regularly, perhaps several times a week, the calculation shifts. You are more likely to want the water ready, the temperature maintained, and the experience to require minimal setup each time. That points toward an electric or hybrid model, where heating and filtration run automatically and the tub stays ready for use without any active management between soaks.

Neither pattern is better. They reflect different lives and different ways of using the time you have. Understanding your own rhythm honestly is the most reliable starting point for getting the decision right.

A question worth sitting with

Is the tub an occasional event you want to look forward to, or a standing part of your weekly routine? The answer shapes everything that follows.

Think about your property

Where the tub will live has a direct bearing on which model makes sense. AlumiTubs are compatible with every property type, but different properties suit different systems.

Off-grid and remote properties

A wood fired AlumiTub requires no electricity and no infrastructure beyond a flat surface and a water supply. This makes it the obvious choice for off-grid cabins, lakeside retreats, island properties, and anywhere that mains power is either unavailable or impractical to connect. The tub arrives pre-assembled, can be rolled into position by one or two people, and measures thirty-eight inches on its side, which means it can navigate most gates, narrow paths, dock access, and even boat transport to reach its final location.

For remote properties where the view is the whole point, the wood fired model has another advantage: it can go wherever the view is best. An electric or hybrid tub depends on a power connection, which often means placing the tub closer to existing infrastructure rather than the optimal spot on the land, unless you're up to the task of trenching a hardwired connection further from the house. 

Primary residences and urban properties

For a primary residence with reliable mains power, all three models are viable. The electric model is the most straightforward for everyday use: the heating and filtration run automatically, the water stays clean and at temperature, and there is no active management required between sessions. It is the closest equivalent to a conventional spa while keeping the materials, craftsmanship, and outdoor character that make an AlumiTub what it is.

For those who want the experience of a wood fired tub but also need the tub to function reliably through periods of inattention, a cold winter, or a fire ban, the Hybrid is designed precisely for that situation. It gives you both: the ritual of the fire when you want it, and the consistency of electric heating and filtration when you need it.

Properties with seasonal fire restrictions

If your property is in a region with seasonal fire bans, a wood fired only model will be out of use for part of the year. This is worth factoring in honestly. The Hybrid solves the problem directly: the electric system keeps the tub heated, filtered, and protected during periods when the wood fire cannot be lit. The wood fired experience remains available through the rest of the year.

Short-term rental and guest properties

For properties that host guests, the Hybrid and Electric models offer a meaningful practical advantage. Water can be maintained clean and at temperature between guest arrivals without requiring anyone to be on site to manage it. Freeze protection engages automatically when temperatures drop. The tub stays in a ready state without hands-on management, which is exactly what a rental property needs.

 

Water access: an often-overlooked consideration

Every hot tub needs water. This sounds obvious, but water access shapes more decisions than people typically anticipate before buying.

For most residential properties, a garden hose connection is all that is needed. Fill the tub, use it, drain it. For a wood fired model used without filtration, this happens with each use. For electric and hybrid models with built-in filtration, the water is maintained between uses and the fill cycle is far less frequent.

For off-grid and remote properties, the question is more involved. A battery-powered pump can draw water from a lake, river, or the ocean. AlumiTubs are saltwater compatible, which makes filling from a saltwater source a practical option for coastal and island properties. Some owners choose to add a low-voltage filtration system even to a wood fired tub specifically to reduce water usage: a single fill can be maintained cleanly for months at a time rather than draining and refilling after each use.

The practical question to ask is: how will I get water to this tub, and how often do I want to manage that? If the answer involves any complexity, it is worth solving before the tub arrives.

 

Choosing the right size

AlumiTubs are available in three sizes. The standard depth across all three is thirty-eight inches, which is enough to comfortably cover adult shoulders. A deeper forty-four inch option is available on all three sizes across all heating systems, and a forty-eight inch option is available on electric models.

Model	Diameter	Standard depth	Depth options	Suits
Small	5 ft	38 inches	44 in (all heating types); 48 in (electric)	1 to 2 people
Standard	6 ft	38 inches	44 in (all heating types); 48 in (electric)	2 to 6 people
Large	7 ft	38 inches	44 in (all heating types); 48 in (electric)	Larger groups and families

 

The heat-up time difference between each size is around one hour to 90 minutes. Each hold their temperature well once reached, requiring only a modest amount of wood to maintain warmth through a long soak, or automatically to the temperature its set to on the Electric and Hybrid systems. 

The guidance here is simple: think about how the tub will most often be used, not its theoretical maximum. The Small suits solo soakers or couples with tighter spaces or access constraints. The Standard suits most households very comfortably. The Large is worth considering if the tub will regularly be used by larger groups, if it is going into a guest property where several people may be soaking at once, or if you simply want more room.

Because the size difference has minimal impact on running costs or day-to-day experience, it is generally worth future-proofing the decision. If there is a reasonable chance you will want more space, the Large removes that doubt from the outset.

 

Choosing the right heating system

This is where the three models diverge, and it is worth understanding each one clearly before deciding.

Wood Fired

The wood fired model is the original AlumiTub. It requires no electricity, operates completely off-grid, and creates a soaking experience built around the ritual of the fire. You light it, tend it, and by the time the water is hot you have already slowed down. For many owners, this process is not an inconvenience. It is the whole point.

It is the right choice if you want a simple, elemental soaking experience and the act of heating by fire feels like part of that. It suits seasonal or intermittent use well, and it can go to locations where no other model can.

For those who prefer not to drain and refill after every use, a low-voltage 120V plug-and-play filtration system can be added. This keeps the water clean for months at a time without changing the off-grid character of the tub or requiring a hardwired connection.

Electric

The electric model is designed for regular, consistent use at a primary residence. Heating and filtration are built in and run automatically. The water stays at temperature and stays clean. There is no fire to light and no active management between soaks.

It is the right choice if the tub will be used frequently, if you want a set-and-forget experience, and if the property has a reliable power connection. For those who manage properties remotely, the electric model's automatic freeze protection and temperature control are particularly useful.

Hybrid

The Hybrid was designed for owners who want both. It combines a wood fired firebox with an electric heating and filtration system, and neither compromises the other. Light the fire when you want the ritual. Let the electric system maintain temperature, filter the water, and protect the tub through winter when you do not.

It is the right choice if you want year-round residential use without giving up the wood fired experience, if your property sits in an area with seasonal fire restrictions, or if you manage a guest property that needs to stay ready between visits.

One thing worth knowing about all three models: the heating systems are interchangeable. If your circumstances change, a different heating method can be added later. The tub itself is designed to last for decades. The system powering it can evolve alongside the life being lived around it.

What to prepare before your tub arrives

AlumiTubs are built to order by hand on the Sunshine Coast of Canada. Lead times of several months are common, and reserving early secures your position in the production queue. That lead time is genuinely useful, because it gives you time to prepare the site properly so that when the tub arrives, you can be in the water the same day.

Site

Any flat, stable surface works. Compacted gravel, concrete, or paving are all reliable choices. If the tub is going onto a deck, confirm the structure can support the weight of a filled tub before it arrives. Allow two to three feet of clear space on all sides, and confirm there is at least ten feet of chimney clearance from any flammable structure above for wood fired and hybrid models.

Access

Plan the route from the delivery point to the final position. The tub travels on its side and measures thirty-eight inches in that orientation, which is enough to pass through most gates and doorways. Walk the route in advance and remove anything that could complicate the roll-in on delivery day.

Water

Confirm how the tub will be filled and, if relevant, how the water will be drained. For off-grid properties, source the pump or filling solution before the tub arrives. For properties using filtration, plan for how water changes will be managed seasonally.

Power

For electric and hybrid models, a hardwired connection needs to be in place before the tub arrives. Running cable after the fact can be disruptive and costly. If the tub is going at a distance from existing circuits, factor in the trenching required and get it completed during the lead time.

Wood

For wood fired and hybrid models, have a supply of seasoned hardwood ready for the first use. Dry, dense hardwood, oak, ash, or maple, gives the most efficient burn and the shortest heat-up time. Green or wet wood will disappoint on the first soak. For guidance on what to source, see the companion guide on the best wood to use.
