Rough vs Smooth Finish Salt Bricks: Look, Light, Upkeep and Cost

Rough and smooth salt bricks are the same mineral with a different face. A smooth, polished face tends to show crystal veining clearly, gives a soft sheen and is easier to dust. A rough or natural face scatters light into a more matte, textured surface with visible shadows, but it gathers more dust and can make joint lines harder to keep even. Natural Salt Co. lists its 8 x 4 x 2 in pink salt bricks with a smooth polished face, at about $5.53 to $6.60 per brick depending on pack size.

What "rough" and "smooth" mean on a salt brick

Finish describes the visible face of the brick, the side that faces the room. It does not change the salt itself, the size or the weight.

• Smooth or polished face: the face is flat and polished. Our product pages describe it as "smooth polished with natural crystalline texture," so you still see the natural mineral pattern, just on a flat surface.
• Rough or natural face: the face is left split, chiseled or uneven. Depth varies across the brick, so light and shadow change from piece to piece.

Color and veining vary with both finishes. Our pages note that tone, pattern, surface and translucency differ from brick to brick, so photos are a guide, not a promise of an exact match. For how color choice affects the look, see our guide to pink vs white salt bricks and tiles.

Rough vs smooth salt bricks compared

Factor	Smooth (polished) face	Rough (natural) face
Overall look	Clean, modern, even surface	Rustic, cave-like, more texture
Front lighting	Soft sheen; veining reads clearly	Shadows and highlights across the face; reads more matte
Backlighting	Glow tends to look more even across each brick	Glow tends to look patchier because thickness varies
Dusting	Easier to wipe with a dry cloth	Dust can settle in crevices
Joint lines	Easier to keep faces flush and joints even	Uneven faces can hide small level differences, but joints look less uniform
Wall depth	Consistent 2 in depth on our bricks	Depth can vary from brick to brick
Typical fit	Living rooms, offices, retail, backlit feature walls	Rustic or cave-style rooms, accent panels where texture is the goal

These are general design differences, not lab measurements. How a finished wall looks depends on the bricks you receive, your lighting and the installer.

Which finish fits your room?

Choose smooth if

• You plan to backlight the wall and want an even glow. Our product pages describe the bricks as semi-translucent and suited to backlighting. Our backlit salt wall lighting layout guide covers LED planning; have a licensed electrician handle the wiring.
• The space is busy or public, like a lobby, salon or shop, and the wall needs regular dusting.
• You want straight, consistent joint lines that suit a modern interior.

Consider rough if

• Texture and shadow matter more to you than an even glow.
• The wall is mostly front lit, with spotlights or wall washers that rake across the surface.
• The room has a rustic or natural stone style and the wall gets little hand contact.

Natural Salt Co. currently lists its bricks with a smooth polished face. If your design calls for a rough or rock-face finish, contact us before ordering to ask what can be supplied. We have no verified price for rough-face bricks, so we don't compare their cost here.

Smooth salt brick prices per brick and per sq ft

Store prices for our pink salt bricks, with approx. cost per brick (pack price divided by bricks) and per sq ft (per brick cost times 4.5).

Pack	Approx. price	Approx. per brick	Approx. per sq ft
Single brick	approx. $6.60	about $6.60	about $29.70
Pack of 20	approx. $130	about $6.50	about $29.25
Pack of 30	approx. $185	about $6.17	about $27.75
Pack of 50	approx. $287	about $5.74	about $25.83
Pack of 70	approx. $387	about $5.53	about $24.88
Pack of 100	approx. $577	about $5.77	about $25.97

Prices checked October 21, 2026. All prices are approximate and can change; see the product page for the current price.

The pack of 70 has the lowest approx. per brick cost at these prices. The pack of 100 costs slightly more per brick than the packs of 50 and 70, so buying a larger pack does not automatically lower the cost per brick.

Example budgets for a smooth brick wall

These examples add a 10% allowance for cuts and breakage, round up to whole bricks and use the lowest-cost pack mix we found at the checked prices. Adhesive uses our 3-tube pack (approx. $80), which its product page lists for up to 120 salt bricks.

Wall	Bricks needed	Pack mix	Approx. brick cost	Approx. adhesive	Approx. total
4 x 6 ft (24 sq ft)	119	70 + 50 (120 bricks)	approx. $674 (about $28 per sq ft)	one 3-pack, approx. $80	approx. $754
8 x 10 ft (80 sq ft)	396	five 70s + one 50 (400 bricks)	approx. $2,222 (about $28 per sq ft)	four 3-packs, approx. $320	approx. $2,542

Installation tips that depend on finish

• Lay out a dry run. Natural tone varies, so spread bricks out and mix them before setting. This matters most on smooth walls, where color shifts are easy to spot.
• Check the back face. Adhesive bonds to the back of the brick, not the decorative face, so finish has little effect on bonding. Follow the adhesive maker's instructions.
• Plan cuts. Cut edges on a polished wall can look different from factory edges. Place cut pieces at corners or ends. Our guide to cutting salt bricks and tiles explains the method.
• Keep it dry. Salt reacts to moisture with either finish. Dust with a dry cloth and avoid wet cleaning.
• Confirm the structure. Have a qualified contractor confirm that the wall or base can carry the load.
