Finnmark Sauna Accessories
About This Collection
Shop Finnmark sauna accessories for FD-1 through FD-5, including model-specific waterproof sauna covers and comfort cushions for Finnmark sauna benches. These accessories are designed to help complete and protect your Finnmark setup while keeping compatibility easy to understand.
Because Finnmark models differ in size and cabin design, accessories should be selected for the specific sauna model you own. Browse the collection by FD model to find the appropriate cover or bench cushion for your sauna.
Finnmark Sauna Accessories for FD-1 Through FD-5
Finnmark accessories are made around specific sauna models rather than one universal cabin size. This collection brings together accessories for the Finnmark FD-1, FD-2, FD-3, FD-4 Trinity, and FD-5 Trinity XL so you can shop by the model you already own or plan to purchase.
The current assortment includes waterproof sauna covers and comfort seat cushions for Finnmark sauna benches. Keeping these products in one dedicated collection makes it easier to identify the accessory intended for your exact sauna model.
Finnmark Sauna Covers and Bench Cushions
Finnmark waterproof sauna covers are model-specific, so the correct cover should match the dimensions and design of the sauna it is made for. Choosing by FD model helps avoid relying on a generic cover that may not fit the cabin properly.
Finnmark sauna cushions provide an additional comfort option for the bench. Like the covers, cushion sizes vary across the Finnmark lineup, so compatibility should be checked against the sauna model before ordering.
Find the Right Accessory for Your Finnmark Model
Start with the model number of your sauna. An FD-1 accessory should be matched with an FD-1 sauna, while accessories labeled for FD-2, FD-3, FD-4, or FD-5 should be paired with their corresponding models.
If you are purchasing a sauna and accessories together, choose the sauna first and then select the matching accessories. This keeps the buying process simple and helps ensure the products are intended to work with the same Finnmark cabin.

Finnmark Sauna Accessory FAQs
Are Finnmark sauna covers made for specific FD models?
Yes. Finnmark describes its protective covers as customized accessories for its sauna models, and the available covers differ in size depending on whether you own an FD-1, FD-2, FD-3, FD-4 Trinity, or FD-5 Trinity XL.
Match the cover to the exact FD model rather than choosing only by seating capacity. The cabins have different exterior dimensions, so the model number is the most reliable way to confirm fit.
Can a Finnmark sauna be installed outdoors with a waterproof cover?
Finnmark allows outdoor placement when its installation requirements are followed. The manufacturer states that an outdoor sauna must use a protective cover and should be placed on sturdy, dry, level ground.
Finnmark's outdoor-cover instructions also require the sauna to be positioned under an awning or overhang so heavy rain does not fall directly onto the roof or cover. The cover should therefore be treated as one part of the outdoor installation, not as the only protection required.
Which Finnmark sauna cushion fits my model?
Finnmark sauna cushions are sized differently across the FD lineup. Current published dimensions are approximately 20" × 30" × 2.5" for FD-1, 20" × 41" × 2.5" for FD-2, 20" × 65.5" × 2.5" for FD-3, 17" × 44" × 2.5" for FD-4, and 17" × 68" × 2.5" for FD-5.
Choose the cushion carrying the same FD model number as your sauna rather than assuming that cushions from similarly sized cabins are interchangeable.
What are Finnmark sauna cushions made from?
Finnmark's current sauna cushions use non-toxic marine-grade vinyl over a 2.5-inch non-toxic foam insert. The vinyl is designed for durability in a sauna environment and provides a wipeable seating surface.
The cushions are intended as comfort accessories for the sauna bench and are available in different lengths to match the Finnmark FD models.
How should I care for a Finnmark waterproof sauna cover?
Current Finnmark cover instructions call for surface cleaning rather than machine washing. Use mild soap and water to wipe the cover and allow it to hang dry.
When the sauna is not in use outdoors, Finnmark also instructs owners to keep the cover's snap buttons secured and the zippers closed.
Does using a Finnmark cover mean weather damage is covered by the sauna warranty?
No. A Finnmark cover helps protect the sauna, but the manufacturer's warranty documentation states that damage caused by natural weather conditions is not automatically covered even when the factory-authorized outdoor cover is used.
For outdoor installations, follow Finnmark's placement, drainage, cover, and clearance requirements in addition to using the correct model-specific cover.
Can I buy Finnmark accessories before choosing my sauna?
It is better to choose your Finnmark sauna model first. Covers and cushions vary across FD-1 through FD-5, so knowing the exact model makes it much easier to select compatible accessories.
If you are still deciding between models, compare our Finnmark saunas first, then return to this collection to select the matching cover or cushion.
