The sleek, modern design of the Narvi Slim has great potential for innovative sauna design. The Slim can be fitted with ease, either on a high base or recessed into the sauna benching. The bench collar or high base are available in the Sauna Accessories section of our site. The Narvi Slim is also a great choice as a freestanding heater for narrower sauna rooms. In order to provide to accommodate for the narrower design without compromising on Narvi’s renowned löyly, this heater has a greater width which has the added benefit of spreading the heat more evenly throughout the sauna.
This heater looks great in both modern and traditional sauna designs and comes with a separate control unit which is a stylish and practical way to accurately control the sauna temperature. This control unit can be fitted outside the sauna too. The heater is also compatible with other control units and thus is available as a standalone. However, please note that a control unit is required for this heater to function.
The addition of white cover stones to the heater will ensure an elegant, refined sauna experience. The heating elements of Narvi electric sauna heaters have an exceptionally large diameter (8.5 mm), improving the durability of the product and increasing its lifespan, as well as reducing the chance of overheating significantly.
The Slim can be safely and stylishly installed within sauna benching with the use of an installation flange. To install the Narvi Slim within raised benching, you will also require the Narvi Slim Raised Installation Base.
This heater must be installed by a qualified electrician and can be easily installed on both single phase and three phase power supplies.

About Narvi Oy
All Narvi sauna heaters are CE tested and bear the Finnish Key Flag Symbol. This is awarded to sauna heaters that are made and designed in Finland, where over 95% or more of the production must be within Finland itself. There are many brands that claim to be made in Finland but are actually made in the Far East or Russia and merely assembled or labelled in Finland. Watch out for these symbols as a mark of an authentic, Finnish-made, safe, quality product:
As part of Finnmark Sauna's Endurance Ethos, we only deal with products that are market leaders in quality. We commit ourselves to search exhaustively for the highest quality authentic Finnish sauna products.
Please note, we recommend that sauna heaters should be installed by a suitably qualified electrician/builder/fitter. Finnmark Limited accepts no liability for loss or injury caused by the incorrect installation or misuse of your sauna heater. Please Contact Us if you require information on our recommended fitters.

Receiving goods and reporting damage
*The customer must inspect the goods upon receipt and report any damage or issues within 48 hours of receiving the goods.*
Occasionally during shipment an item may incur some damage in which case you must CALL US or EMAIL US at firstname.lastname@example.org and make a claim within 48 hours of receiving shipment. Please do not refuse delivery of an entire shipment due to damage of a particular item, as this will greatly delay replacement of damaged merchandise. Due to shipping and delivery company policies all damage claims WILL BE DENIED if you do not notate on the delivery receipt that the boxes are damaged at the time of delivery.
KEEP ALL BOXES UNTIL A CLAIM HAS BEEN CLOSED.
IMPORTANT: Prior to signing you must write a note that there is damage to the boxes on the delivery receipt in order for any Damage Claim to be accepted. Writing "subject to inspection" or "Not Checked" is not acceptable and WILL NOT allow you to file a claim later if you find damage when the boxes are opened.
IMPORTANT: COUNT AND CONFIRM THAT THE TOTAL BOXES YOUR RECEIVE MATCHES THE NUMBER ON YOUR DELIVERY RECEIPT BEFORE SIGNING.
If 1 or more boxes are missing you MUST make a note on the Delivery receipt indicating how many boxes are missing. If you accept and sign that you received all the boxes without writing on the Delivery receipt that 1 or more boxes are missing...we are unable to replace any missing items as the delivery company will not accept a claim for the missing box(s).
Making a damage claim

All customer requests for repair or replacement of any item are required to include photos in order to fulfill your requests. Photos are required to confirm the extent of damages for the manufacturer to determine if replacement parts or a full unit replacement is required.
Please follow the directions below to submit a Damage Claim.
1. All damage claims emails or calls must be submitted within 48 hours of receipt of order.
2. Email a claim request to firstname.lastname@example.org with as much detail as possible.

We encourage our customers to accept their order despite the condition of any one item at delivery but to notate all package damage on the paperwork provided by the delivery driver. This is because a refusal of a damaged shipment can increase the time it takes to process replacements. Most often when damage is found within a shipment, it usually is on only one item. Accepting the shipment allows the customer to receive all the undamaged items and will greatly reduce the time to process the damaged replacement item.
If a full replacement unit is sent, the original item becomes the property of Finnmark Limited. Occasionally our carrier may pick up the damaged or defective items for inspection. Because of this, all items must be kept in their original packaging until further instructions from a Finnmark Limited claim team member is given.
Claims for missing items or goods damaged in transit after 48 hours from receipt will not be accepted. It is important that any claims for damaged goods are reported with photographic proof at the point the claim is reported. All damage claims should be made to: email@example.com
