How much does 6-person spa hot tub weigh?

One of the most crucial issues when purchasing or installing a 6-person spa hot tub is its weight. Weight not only affects transportation and handling but also directly relates to the structural load-bearing capacity of the installation location. This is especially true when the hot tub is installed on a terrace, balcony, platform, or indoor floor. Understanding its weight is key to ensuring safety, budget planning, and determining the installation plan.

Many consumers often ask: How much does a 6-person spa hot tub weigh?

What is its dry weight? What is its weight when filled with water? What factors affect the weight of a spa hot tub?

—LOVIA SPA is one of China's well-known outdoor spa hot tub brands. Our 6-person spa hot tub measures 2300×2300×880 mm, with a dry weight of 350 kg and a weight of 2190 kg when filled with water.

How much does a 6-person spa hot tub typically weigh? (Dry/Wet Weight Range)

The weight of a 6-person spa hot tub varies greatly depending on the brand and structure, but the industry average can be used as a reference:

✔ Typical dry weight range for a 6-person spa hot tub:

270–430 kg

✔ Wet weight range when full of water:

1800–2600 kg

The reason for such a significant weight difference is that the water volume inside a hot tub is usually between 1300–1800 liters, and water itself is very heavy (1 liter of water ≈ 1 kg). Therefore, the wet weight is several times the dry weight.

How much does a 6-person spa hot tub at LOVIA SPA actually weigh?

LOVIA SPA product specifications are as follows:

• Product dimensions: 2300×2300×880 mm

• Dry weight: 350 kg

• Weight with water: 2190 kg

• Brand background: Founded in 1989, LOVIA SPA is one of China's most renowned and largest manufacturers of spa bathtubs and swimming hot tubs.

The dry weight of the LOVIA SPA 6-person spa hot tub is approximately 350 kg.

The total weight with water is approximately 2190 kg (approximately 2.19 tons).

This is a very typical weight range for a high-end 6-person spa hot tub, especially suitable for installation in outdoor patios, sturdy platforms, or professionally designed outdoor areas.

Why is the weight of a 6-person spa hot tub so important?

Weight is a key factor affecting installation safety, stability, and long-term lifespan. Whether the hot tub is installed on the ground, a patio, or a wooden platform, load-bearing capacity must always be a priority.

Reasons for the importance of weight include:

1. Load-bearing safety

A spa hot tub weighing over two tons when fully loaded will generate very high static pressure

→ Insufficient ground load-bearing capacity can lead to structural deformation or cracks.

2. Installation cost planning

Heavier spa hot tubs are more likely to require:

• Mechanical hoisting

• Reinforced subgrade

• Custom-made load-bearing structures

These will all affect the budget.

3. Transportation method selection

Weight determines:

• Whether manual handling is possible

• Whether forklifts or cranes are needed

• Whether the access path is large enough

4. Location planning

Once a spa hot tub is installed, it is rarely moved, so careful planning is essential before installation.

What is the dry weight of a spa hot tub?

Why is there such a large difference in dry weight?

Dry weight = Weight of the empty bathtub itself

It is composed of the following materials:

• Acrylic (bathtub body panel)

• Fiberglass support layer

• Stainless steel or wood frame

• Plumbing system

• Bottom shell

• Insulation material

• Nozzle system

• Control panel and motor compartment

Why do dry weights vary?

1. Material thickness: High-end brands use thicker acrylic and support layers, resulting in greater weight.

2. Number of nozzles: More nozzles and more pump systems mean greater weight.

3. Internal structural strength: High-strength frames (such as steel structures) are heavier than wooden frames.

4. Insulation materials: Full foam insulation design > Semi-foam design > Cavity insulation

(Weight difference can reach 15–60 kg)

Why does the weight of a spa hot tub increase dramatically when filled with water?

The answer is very simple: water is extremely heavy.

1 liter of water ≈ 1 kg,

1000 liters of water ≈ 1000 kg,

which is 1 ton.

The water capacity of a 6-person spa hot tub is typically:

• 1200–1800 liters (of water)

Therefore, the wet weight is usually 5–6 times the dry weight.

For example, using data from LOVIA SPA:

• Dry weight: 350 kg

• Weight when full: 2190 kg

Estimated water weight (2190 – 350):

Water weight ≈ 1840 kg

That is approximately 1840 liters of water.

This perfectly matches the standard capacity of a high-end 6-person spa hot tub.

Does a larger 6-person spa hot tub necessarily mean a heavier weight?

Intuitively, it seems that a larger size means a heavier weight, but the reality is not so simple.

The key factors affecting weight are not external dimensions, but rather:

1. Internal water depth: Deeper spa hot tubs require more water, resulting in higher wet weight.

2. Material density: High-quality acrylic + fiberglass support layers are heavier than lower-end materials.

3. Insulation layer structure: Fully foam-filled designs significantly increase dry weight.

4. Number of motors: Multi-pump, high-power jet systems are heavier than single-pump systems.

5. Internal seat curves: More complex ergonomics → thicker structure → greater weight.

✔ Therefore: Larger size ≠ necessarily heavier weight. Materials, structure, and internal water depth are the key factors determining weight.

How much does a 6-person spa hot tub filled with water weigh?

How to calculate wet weight?

Wet Weight = Dry Weight + Water Weight + User Weight (if in use)

Calculation steps are as follows:

Step 1: Determine Dry Weight

LOVIA SPA Dry Weight: 350 kg

Step 2: Calculate Water Capacity Weight

Water capacity is calculated in liters

1 liter = 1 kg

Assuming water capacity = 1800 liters

Water weight ≈ 1800 kg

Step 3: Add Up Wet Weight

Wet Weight = 350 kg + 1800 kg

Wet Weight ≈ 2150 kg

✔Conclusion: The wet weight is typically around 2 tons.

Any installation location must be able to withstand a static weight of at least 2200–2500 kg.

How does the material of a 6-person spa hot tub affect its weight?

Which material is the heaviest?

Different materials have different densities, therefore the weight difference is significant.

Common Material Weight Ranking (Heaviest to Lightest):

1. Full Foam Insulation + Thickened Acrylic + Stainless Steel Structure (Heaviest)

2. Fiberglass + Wood Structure

3. Composite Material Structure

4. Plastic Shell (Lowest Price, Lightest)

LOVIA SPA is a high-end product, using a robust structure and high-quality acrylic, resulting in a dry weight of 350 kg, consistent with the weight characteristics of a high-quality spa hot tub.

Why is the weight of a 6-person spa hot tub so critical for installation location?

A fully loaded spa hot tub weighs over 2 tons, resulting in considerable static pressure.

For safety, the following points need to be considered:

1. Load-bearing capacity

The installation platform must withstand:

• Static weight (bathtub + water)

• Dynamic weight (additional pressure from user activity)

2. Foundation stability

The ground must be flat and firm; otherwise:

• Water level fluctuations

• Nozzle angle misalignment

• Uneven stress on the frame

• Shell deformation

3. Drainage system

Heavy weight means the drainage system must be properly designed; otherwise, drainage may impact the ground structure.

4. Electrical design

Greater weight → More water → Greater power

Therefore, a stable power supply system is essential.

Is a 6-person spa hot tub suitable for a balcony or roof?

Generally speaking:

✔ It is not recommended to place a spa hot tub exceeding 2 tons directly on a typical residential balcony or roof.

Reasons:

• Typical residential balconies have a load-bearing capacity of only 250–350 kg/m²

• A 6-person spa hot tub has a wet weight exceeding 2 tons

• Installation may lead to structural risks

If the user insists on installation in a high-rise location, the following should be conducted:

• Load-bearing assessment by a professional structural engineer

• Foundation reinforcement design

• Construction of a reinforced steel support structure
