Salt Tile Thickness: 1 Inch Tiles vs 2 Inch Bricks Compared

For most adhered feature walls, a 1 inch salt tile is the lighter, slimmer choice: it adds about 13 lb of salt per square foot and sits about 1 inch off the wall before adhesive. A 2 inch salt brick adds about 24.75 lb per square foot and about 2 inches of depth, which suits stacked walls, sauna-style builds and walls where you want a heavier, chunkier look. Both cover about 4.5 pieces per square foot, and at prices checked October 16, 2026, both land at roughly $24 to $30 per square foot in pink salt, depending on the pack.

Salt tile thickness at a glance

In the Natural Salt Co. store, the 1 inch option is the salt tile (8 x 4 x 1 in) and the 2 inch option is the salt brick (8 x 4 x 2 in). They share the same 8 x 4 inch face, so the wall looks the same size from the front. The difference is depth and weight. The specs below come from our product pages (store data).

Spec (store data)	1 inch salt tile	2 inch salt brick
Size	8 x 4 x 1 in	8 x 4 x 2 in
Weight per piece	2.9 lb	5.5 lb
Pieces per sq ft (8 x 4 face showing)	4.5	4.5
Salt weight per sq ft (4.5 x piece weight)	about 13.05 lb	about 24.75 lb
Coverage of a 50-pack	about 11.11 sq ft	about 11.11 sq ft
Depth added to the wall, before adhesive	about 1 in	about 2 in

The 4.5 pieces per square foot figure comes from the face size: 8 x 4 inches is 32 square inches, and 144 divided by 32 is 4.5. The weight per square foot is our own calculation from the listed piece weights. For the full size breakdown, see our salt tile sizes guide or the salt tile size guide page.

Weight and wall load: 1 inch vs 2 inch

Thickness roughly doubles the load. A 2 inch brick weighs about 1.9 times as much as a 1 inch tile (5.5 lb vs 2.9 lb), so the same wall carries almost twice the salt. Here is the installed salt weight for three example walls, before adhesive and backing.

Wall size	Area	1 inch tiles (13.05 lb/sq ft)	2 inch bricks (24.75 lb/sq ft)
4 x 6 ft	24 sq ft	about 313 lb	about 594 lb
6 x 8 ft	48 sq ft	about 626 lb	about 1,188 lb
8 x 10 ft	80 sq ft	about 1,044 lb	about 1,980 lb

These are planning numbers, not a structural rating. Before ordering, it is a good idea to have a contractor or engineer confirm that the wall, backing and any base or ledger can carry the load, and to follow the adhesive maker's instructions. Our salt brick wall weight guide walks through the load math in more detail.

Wall depth, trim and outlets

Depth is the thickness difference people tend to notice after the wall goes up. A tile wall sits about 1 inch proud of the surface plus the adhesive layer; a brick wall sits about 2 inches plus adhesive. A few things to check before you choose:

• Outlets and switches: boxes may need extenders so plates sit flush with the new face. An electrician can confirm what your local code allows.
• Door and window casing: a 2 inch face can stand past standard casing, so plan how the edge meets the trim or finish it with a frame.
• Tight spaces: in hallways, behind doors or beside a bed, the extra inch of a brick can matter.
• Backlit builds: an LED backlit wall usually needs its own cavity or panel behind the salt, so total depth depends on the lighting system you choose. See our backlit salt wall planning guide.

How thickness affects backlighting

Our tile product page describes the 1 inch tiles as semi-translucent and backlight optimized. In general, light has less salt to pass through in a thinner piece, so the same LEDs may read brighter through a 1 inch tile than through a 2 inch brick. A brick can still glow, but it may need brighter or closer lighting to look similar. Natural salt varies in color and veining from piece to piece, so glow varies too. If backlighting is the main goal, it can help to test a few pieces with your chosen LEDs before ordering a full wall.

Approx. cost per square foot by thickness

Thicker does not mean more expensive per piece in every pack. Here are the pack sizes both products share, with the approx. price per piece and per square foot at 4.5 pieces per square foot. Prices are store data from our live collection pages.

Pack	1 inch tiles: approx. price	Approx. per tile	Approx. per sq ft	2 inch bricks: approx. price	Approx. per brick	Approx. per sq ft
Single	$6	$5.99	$27	$7	$6.60	$30
20	$117	$5.84	$26	$130	$6.50	$29

Prices checked October 16, 2026. All prices are approximate and can change; see the product page for the current price.

What the numbers show:

• In single, 20 and 30 packs, tiles cost less per piece than bricks.
• In 50 and 70 packs, bricks cost slightly less per piece than tiles (about $5.74 vs $5.80, and about $5.53 vs $5.71).
• In 100-packs, tiles are slightly lower (about $5.72 vs $5.77). For both products, the 100-pack costs a little more per piece than the 70-pack.
• Tiles also come in 150, 200 and 300 packs at roughly $5.33 to $5.40 per tile, which is where larger tile orders get lower per piece.

Example walls: 1 inch tiles vs 2 inch bricks

Each example adds a 10% allowance for cuts and breakage, then rounds up. The pack mix is the lowest-cost combination of listed pack prices we found for at least that many pieces.

Wall	Pieces with 10%	1 inch tiles: pack mix	Approx. cost	2 inch bricks: pack mix	Approx. cost
4 x 6 ft (24 sq ft)	119	100 + 10 + 4 + 4 + 1	$684	70 + 50 (120 bricks)	$674
6 x 8 ft (48 sq ft)	238	200 + 30 + 4 + 4	$1,293	3 x 70 + 20 + 8 singles	$1,344
8 x 10 ft (80 sq ft)	396	2 x 200 (400 tiles)	$2,142	5 x 70 + 50 (400 bricks)	$2,222

Prices checked October 16, 2026. All prices are approximate and can change; see the product page for the current price.

At these sizes the material cost is close: about $10 lower in bricks for the 4 x 6 ft wall, and about $51 and $80 lower in tiles for the 6 x 8 ft and 8 x 10 ft walls. Since cost is so close, weight, depth and lighting usually decide the thickness.

Adhesive, cutting and install differences

Our adhesive product page says one tube covers 30 to 40 salt bricks. We use that range as a planning estimate for tiles too, so the 4 x 6 ft example needs about 3 to 4 tubes either way, and the 8 x 10 ft example about 10 to 14 tubes. You can order tubes from our pink salt adhesive page.

• Adhered walls: both thicknesses can be bonded to a suitable backing. The lighter tile puts less load on the adhesive and backing.
• Stacked walls: a 2 inch brick has more bearing surface when stacked on a base, so bricks are the usual pick for stacked builds. See stacked vs adhered salt brick walls.
• Cutting: a 1 inch tile has half the depth to cut through, and a 2 inch brick needs a blade with enough cutting depth. Our salt cutting guide covers tools and technique.
• Handling: a 2.9 lb tile is easier to hold in place while adhesive grabs than a 5.5 lb brick, which may make tall walls easier to set.

Which thickness fits your project?

Project	Thickness to consider	Why
Adhered feature wall in a home or office	1 inch tiles	About half the weight and depth
Backlit panel or headboard wall	1 inch tiles	Thinner salt for light to pass through
Stacked wall on a base	2 inch bricks	More bearing surface per piece
Dry sauna or chunky, textured look	2 inch bricks	Deeper, heavier build
Large tile order (150+ pieces)	1 inch tiles	Larger tile packs listed at roughly $5.33 to $5.40 per tile
