Clean Lines, Furniture-Quality Finish

The Prosaunas Aspen 1x1 Trim brings a polished, defined look to your sauna interior. Smooth on all four sides with eased edges, this 21 × 21 mm trim piece delivers the refined detailing that elevates a sauna from functional to beautifully crafted.

Why Aspen Belongs in Your Sauna

Aspen is prized as a sauna material because it does not secrete resin, splinter, or overheat — making it as comfortable as it is good-looking. Its naturally light tone and smooth texture give your space an inviting warmth, and its surface takes paint exceptionally well when a custom finish is desired.

Sourced with 55+ Years of Expertise

Prosaunas selects only the finest aspen from Northern Europe and Canada, backed by more than 55 years of experience crafting premium sauna rooms across North America. Every piece meets their stringent quality standards, so the wood that arrives at your door is consistent, carefully chosen, and ready to impress.

Description

This aspen trim is milled smooth on all four sides with eased edges, giving each piece a clean, consistent profile that seats flush against adjoining surfaces without snagging or splintering. At 21 mm × 21 mm, it is sized for finish work — capping raw edges, framing panel joints, and concealing gaps where walls meet benches or ceilings.

Aspen is a traditional sauna wood chosen for its low resin content, which means it will not bleed sap onto bathers or surfaces when heat cycles through the room. Its even, light-toned grain also takes on a uniform aged patina over time, keeping the interior looking cohesive. We offer this trim in 1-foot, 8-foot, and 10-foot lengths so you can order close to what the job actually requires and minimize offcuts.

Key Features

21 mm × 21 mm square profile — compact enough for detail work while still providing solid coverage over seams and raw edges
Smooth 4-sides, eased-edges (S4SEEE) mill finish — consistent surface on every face means no additional sanding before installation
Aspen species — naturally low resin content prevents sap bleed in high-heat sauna environments, protecting both bathers and finished surfaces
Available in three lengths (1 ft, 8 ft, 10 ft) — order the length that matches your run to reduce waste on the job

1'

292 mm length — suited for short infill sections, corner blocks, and detail patches where longer stock would be wasteful

8'

Standard stud-length run — covers most wall-height trim applications in a single unjointed piece

10'

Extended length — reduces the number of joints needed on longer horizontal runs such as ceiling perimeters or bench aprons

SHIPPING & DELIVERY

Sauna wood is not free shipping. Length, piece count, profile, and weight set the rate. These are the Bathing Brands contiguous-US flat rates. Canada is the same table plus $100. Alaska, Hawaii, and remote addresses are quoted.

Checkout charges the 8' piece-count table (contiguous US). Canada is the same table plus $100. Boards over 8' use that same checkout rate; dock or liftgate extras are a follow-up. Alaska, Hawaii, and remote addresses are quoted.

BOARDS UP TO 8'

Under 40 pieces generally ships FedEx Ground in cardboard. Over 40 pieces generally ships LTL with a liftgate on a wood pallet. The longest board in the order sets the rate tier.

Under 19 boards — $195
20–39 boards — $395
40–99 boards — $495
100–299 boards — $695
300–499 boards — $895
500–799 boards — $995
800–999 boards — $1,295

BOARDS OVER 8' UP TO 10'

These lengths ship LTL on a wood pallet. They do not qualify for a liftgate — you need a dock, machinery, or hand offload on site. Carriers allow about one hour to unload before extra fees.

Under 19 boards — $295
20–39 boards — $495
40–99 boards — $595
100–299 boards — $795
300–499 boards — $995

800–999 boards — $1,395

HOW THIS SHIPS

We pack for a safe arrival at the lowest rate that fits the order.
Boards over 8' carry a surcharge because long crates cost more to move than a standard skid.
Heaters, doors, or accessories on the same order can offset some of that freight.

Great Cold Plunge Tub

This is a great cedar-sided cold plunge tub. I spent a considerable amount of time researching cold plunge tubs and wanted one with real ceder wood to fit my sauna room. It also has a durable heat pump, compared to lower-quality chillers. I have had it a few months and no issues. Also, in the pics below, I have the chiller, which is about a 2' x 2' cube plumbed to a different space for a clean sauna room look. I would highly recommend this tub and the price is less than some on the market.

These guys are AMAZING!

These guys are AMAZING! I’d leave 10 stars if I could. We purchased a barrel sauna and cold plunge from them in fall 2025. They were absolutely terrific to work with! Our contractor and electrician had many (many) questions, all were promptly and kindly answered. They even customized our order by selling an extra long cord so we could install control panel inside for extra protection in MN winters. Shipping and delivery was a breeze. We are using our sauna daily and love it! Zero hesitation recommending this company! Thank you Johnny and Mitch for all your help!!!

Harvia Cilindro Half Series 6kW Sauna Heater

What a wonderful sauna!

Researched many saunas for many months. Finally landed on this one. Only complaints i have are the instructions weren't very well written and the trim on the outside was very difficult to put together. We use it almost daily.

Great service, great sauna

Super stoked about the new sauna. I ended up with a beautiful 2-3 person cedar sauna with a huum heater. It’s perfect. These guys were helpful in choosing the right size, type, etc.
very glad I used the cold plunge guys.
