Safety Considerations
Before you start painting or staining your hot tub cabinet, it’s important to take the necessary safety precautions. Here are a few things to keep in mind:
- Wear protective gear: Gloves, eye protection, and a dust mask are essential when working with paint or stain.
- Work in a well-ventilated area: Be sure to work in an area with plenty of fresh air to avoid inhaling harmful chemicals.
- Avoid open flames: Avoid smoking or working near open flames, as paint and stain are flammable.
- Take breaks: Taking frequent breaks can help prevent fatigue and ensure that you stay alert and focused.
By following these safety guidelines, you can help ensure that your project is both successful and safe. With that in mind, let’s move on to the materials you’ll need for the job.
What You’ll Need
Before you begin, gather all the materials you’ll need for the job. This includes:
- Sandpaper (100 and 220 grit)
- Paint or stain of your choice
- Paintbrushes or stain applicators
- Painter’s tape
- Plastic sheeting or drop cloth
- Cleaning solution (such as TSP or vinegar)
- Protective gloves/rubber gloves
- Water
- Rags or sponges
Make sure to choose a paint or stain that is specifically designed for outdoor use and can withstand exposure to water and sunlight. Additionally, if you plan on painting your hot tub cabinet, choose a colour that complements your backyard décor.
Once you have all your materials, it’s time to get started on prepping your hot tub cabinet for painting or staining.

Preparing the Cabinet
Before you start painting or staining your hot tub cabinet, you need to prepare it properly. This step is crucial to ensure that the paint or stain adheres correctly and lasts for a long time.
- Remove previous paint or stain using sandpaper or a chemical stripper. If you are using a chemical stripper, we advise you to test it on a small inconspicuous area first in case it damages your hot tub's finish.
- Remove any dirt or debris from the cabinet using a stiff nylon brush or a power washer.
- Sand the cabinet thoroughly using fine-grit sandpaper to remove any rough spots or splinters.
- Wipe the cabinet down with a damp cloth to remove any dust or debris left behind from the sanding.
Let's go into a bit more depth:
Removing Previous Paint or Stain
Before you begin painting or staining your wooden hot tub cabinet, you need to remove any previous paint or stain. This step is crucial to ensure that your new coat of paint or stain adheres properly and looks smooth and even.
To remove previous paint or stain, you can use a chemical stripper or sandpaper. A chemical stripper is a liquid that you apply to the surface of the wood. It breaks down the previous coating, making it easy to remove with a scraper or steel wool.
If you prefer not to use a chemical stripper, you can sand the surface of the wood with sandpaper. This may take longer and require more effort, but it is a safer and more environmentally-friendly option.
Sanding to Create a Smooth Finish
Sanding is an important part of preparing your wooden hot tub cabinet for painting or staining. Sanding will help create a smoother surface and ensure that the paint or stain adheres to the wood properly.
Start by sanding the entire surface of the cabinet with 100-grit sandpaper, electric sander or palm sander. This type of sandpaper will remove any bumps, splinters, and rough spots on the wood. Continue sanding until you’ve achieved a smooth finish.
Cleaning the Cabinet with Soapy Water and a Damp Cloth
Before you start painting or staining your wooden hot tub cabinet, it’s important that you clean it first. Any dirt, debris, or dust left on the surface of the wood can prevent the paint or stain from adhering properly.
To clean the cabinet, mix a mild soap with warm water and use a damp cloth to wipe down the entire surface of the cabinet. Once you’ve finished wiping it down, dry the cabinet off with a clean, dry microfibre cloth. If your hot tub is on grass and has become caked in mud around the base, you can use a pressure washer to blast any dried debris off.
Wiping Away Dust with a Tack Cloth
Before you apply paint or stain to your wooden hot tub cabinet, it's important to make sure that all dust and debris has been removed from the surface. To do this, you should use a tack cloth. A tack cloth is a special type of cloth that is designed to remove even the finest particles of dust from surfaces.
To use it, run the cloth over the entire cabinet. Once you’ve finished wiping away any dust, repeat the cleaning process with a damp cloth to remove any leftover residue. After that, allow your cabinet to dry completely before proceeding with painting or staining.

Painting or Staining the Cabinet
Now that your wooden hot tub cabinet is clean and ready, it’s time to apply the paint or stain. For best results, you should use paint brushes specifically designed for applying wood coatings - 'synthetic brushes' are usually recommended for this job. This type of brush will help ensure an even, smooth finish.
Before you begin painting or staining, make sure to stir the paint or stain thoroughly to ensure a uniform colour. Start by applying one thin coat of paint or stain to the cabinet, working in small sections. Allow each section to dry completely before moving on to the next one.
Once you’ve finished applying the paint or stain, allow it to dry fully before inspecting your work. If necessary, apply additional coats until you achieve the desired colour and finish.
Choosing a Colour for Your Wooden Hot Tub Cabinet
Before you start painting or staining your hot tub cabinet, you need to choose the right colour. You want to select a colour that complements your garden and blends in well with the surrounding environment. Here are a few things to consider when selecting a colour:
- Figure out your current colour palette. Look at the existing colours in your garden and choose a colour that matches or complements them. We're not just talking about plants here! Look at plant pots, furniture and even fencing to get a grasp of the colours you already use in your landscaping.
- Think about the mood you want to create. For example, if you want a relaxing backyard oasis, you may want to choose a soothing blue or green colour. On the other hand, if you want a natural look, opt for a stain to enhance the cabinet's existing tones and character.
- Consider the climate in your area. If you live in a hot climate (i.e. not the UK!), lighter colours may be a better option as they reflect heat and keep the hot tub cooler. Similarly, darker colours can fade if they receive constant exposure to the sun, so consider how much sun your garden and hot tub receive.
- Think about its position. Is your hot tub shaded below a canopy or is it in front of a fence? Is it going to be surrounded by wood furniture or is it alone in the centre of your garden? Considering the different elements surrounding your hot tub will ensure the final look is cohesive rather than clashy.
Once you have a colour in mind, it’s time to gather the materials you’ll need to complete the project.

Stain vs Paint
Before you start your project, you need to decide whether you want to stain or paint your hot tub cabinet. Both options have their pros and cons, so it ultimately comes down to personal preference.
Stain
Staining your hot tub cabinet can give it a natural, rustic look. It preserves the wood grain and texture while also protecting it from weather damage. Staining also requires less maintenance than paint, as it doesn’t chip or peel.
However, staining does require more prep work, as the wood needs to be sanded and cleaned before applying the stain. It also may require multiple coats to achieve the desired colour and finish.
Paint
Painting your hot tub cabinet gives you more flexibility in terms of colour and finish. It can also provide better protection against weather damage, as it seals the wood and prevents moisture from seeping in.
However, paint requires more maintenance than stain, as it can chip and peel over time. It also covers up the natural texture and grain of the wood, which some people may not prefer.
Ultimately, whether you choose to stain or paint your hot tub cabinet depends on your personal style and maintenance preferences. Whichever option you choose, make sure to choose a high-quality product that is specifically designed for outdoor use.
In Conclusion
In conclusion, painting or staining the cabinet is often a necessary part of wooden hot tub maintenance - but it needn't be a daunting chore. Remember to properly prepare the surface before starting and take your time to ensure even coverage.
With the right tools and techniques, you can have a beautifully finished wooden hot tub in no time!
