Wellness tiles: complete selection guide per 6 zones

By Cretienne Rademaker · Specialist Design & Concept at Tegelmonsters

You choose wellness tiles by zone, not by room. First, determine the anti-slip class and the permissible water absorption, and only then the atmosphere and the look of the material.

A spa, sauna, or treatment room combines wet surfaces, bare feet, and a tranquil appearance. These three requirements guide the tile selection during the design phase.

Wellness frame

What should you look for in tiles for wellness areas?

A wellness area places different demands on a standard bathroom. Bare feet, steam, and fluctuating temperatures come together on surfaces that remain damp all day long. The tile must maintain grip, repel water, and simultaneously convey the tranquility of the space.

The technical basis consists of two standards. For barefoot zones, the anti-slip class according to DIN 51097 applies, which classifies a tile based on the angle of inclination at which a tester with wet feet still maintains grip. For shoe-wearing work zones, the R-value according to DIN 51130 applies. The R-value indicates how slip-resistant a floor is for someone wearing shoes, on a scale from R9 to R13. In a wellness area, the first standard is particularly important, because guests walk barefoot.

The atmosphere is the third requirement, and in a wellness area, it is just as robust as the technology. A calm, natural appearance determines whether a space is perceived as relaxing. Our application page for bathroom tiles offers a starting point for coordinating floor and wall in wet areas, as a wellness area shares much with a high-end bathroom zone.

Zone division

How do you divide a wellness area into zones?

The zone division serves as the compass for the entire specification. A dry changing area requires something different from a swimming ladder, and a steam cabin requires something different again from a treatment room. By dividing the space, you prevent a single tile from being used everywhere it does not technically fit.

The dry entrance and changing area fall under the lightest anti-slip group and should be selected primarily based on comfort and atmosphere. The barefoot path and shower area require higher grip, as there is almost always water present here. The steam cabin primarily requires low water absorption to prevent permanent steam. The swimming pool edge, steps, and jacuzzi floor are in the heaviest anti-slip group. The treatment room is largely dry and should appear warm and tranquil. The technical zone or wellness kitchen relies on the R-value for use with shoes.

Large format plays a distinct role within this framework. Fewer joints result in a calmer surface and less dirt accumulation in wet areas, provided the substrate is sufficiently flat. For the trade-off between format and layability on large surfaces, our analysis of large-format tiles in projects serves as a reference during the specification phase.

Anti slip

Which anti-slip class corresponds to a barefoot zone?

The barefoot anti-slip class is the first technical decision in a wet area. The DIN 51097 standard tests a tile by having a barefoot tester walk across a wet, gradually rising surface until the grip is lost. The angle of inclination at that point determines the class. The steeper the angle, the more grip the tile provides on wet feet.

The three groups correspond to the zones in the framework. Group A applies to dry or occasionally wet barefoot zones such as changing rooms and dry walkways. Group B applies to shower areas, communal showers, and swimming pool edges where water is permanently present. Group C applies to the smoothest and steepest surfaces: swimming ladders, sloping edges, and the bottom of a jacuzzi. Additionally, for areas requiring footwear, you use the R-value, which we have detailed per room type in our guide on R-value and PEI for hospitality spaces.

The standard itself is measurable, but the choice remains a matter of expertise. A non-slip tile is safer on wet feet, but feels rougher and holds slightly more dirt. For the upper limit of swimming pool steps, you therefore consciously choose group C, whereas for the shower area, you often end up with group B. The relevant performance requirements for the slip resistance of floors in buildings are laid down in the Building Decree , which serves as a lower limit for public wellness areas.

Water absorption

How much water can a wellness tile absorb?

Water absorption indicates how much moisture a tile absorbs relative to its weight. The EN 14411 standard classifies ceramic tiles based on this value. The BIa group, with an absorption of up to 0,5 percent, absorbs virtually no water. A tile that absorbs hardly any water remains dimensionally stable in damp conditions, does not freeze and crack in outdoor wellness areas, and retains its color in permanently wet zones.

Porcelain stoneware almost always falls into that dense BIa group. Porcelain stoneware is highly compressed ceramic fired at high temperatures, resulting in a compact and low-porosity surface. This is the logical basis for steam cabins, swimming areas, and outdoor wellness facilities. In addition to absorption, wear resistance plays a role: the PEI value according to ISO 10545-7 indicates on a scale of 0 to 5 how much foot traffic the glaze can withstand, which is relevant in public wellness areas with high foot traffic.

The complete classification by absorption class and the corresponding applications can be found in our selection guide on the water absorption of ceramic tiles . In the Utrecht showroom, we observe that project managers often check this value late in the process, even though they define the material selection early on. We recommend establishing the absorption class together with the anti-slip class during the first specification round.

Atmosphere and look

What look gives a wellness center peace and atmosphere?

The look of a wellness area works differently than that of a formal hall. Here, tranquility takes precedence over tension. A natural stone look offers the natural variation of marble, travertine, or slate without the porosity of real natural stone, and aligns with the biophilic principle that connects a space with nature. A matte finish reflects less light and therefore appears softer than a glossy tile.

At Cersaie 2025 in Bologna and at Coverings, the wellness-relevant trends were clear: matte surfaces, fine relief texture, and a color palette of green-gray, sand tones, and warm terracotta. These colors reappear in both floor and wall tiles and can be combined with tone-on-tone grout for a calm surface. To coordinate tile and grout shades, our guide on grout color for tiled walls or floors offers the combinations used in project architecture. For the color register itself, the approach is outlined in our guide on choosing tile colors for projects.

For curved surfaces and the edge of the pool, small formats work better than large formats, because small tiles follow a curve without the need for cutting. The mosaic tile page lists the common options and their finishes. Aleluia Ceramica from Portugal, known for its design-driven collections, supplies matte natural stone-look series that provide the desired tranquility in a treatment room or shower area.

Maintenance and joint

How do you keep wellness tiles sleek and low-maintenance?

Maintenance starts with the grout, not the cleaning product. A narrow grout joint provides less surface area for limescale and dirt to accumulate, and that is a major factor in a room that is damp all day long. Rectified tiles make that narrow grout joint possible. With rectification, the edges are ground straight to an exact size after firing, allowing the tiles to lie side by side with a grout joint of 2 to 3 mm.

The grout color helps determine how even the surface remains. A warm grey grout requires less maintenance in a wet zone than a white one, because limescale is less noticeable. The combination of dense porcelain stoneware, a matte finish, and a narrow tone-on-tone grout creates a surface that looks sleek for a long time. The background on rectification and grout width can be found in our explanation of rectified tiles.

For wellness tiles, the anti-slip group and maintenance sometimes conflict. A grippier tile from group C is safer on a swimming ladder, but the slightly rougher texture requires more frequent cleaning. In the projects handled by us, designers therefore deliberately choose the highest anti-slip group only in the zones where it is necessary, and keep the dry zones smoother and easier to maintain.

Sample package

How do you put together a sample package for a wellness project?

On the tiles page , you can filter for free by size, look, and finish, and put together a set for each zone. For the shower area, set the filter to a matte tile with sufficient grip; for the treatment room, to a warm natural stone look; and for the pool edge, to a small format. For each zone, then select the application page that most closely matches the project type.

What project managers often tell us: the first filtering round takes place online, followed by a physical assessment in our showroom in Utrecht. The showroom is accessible to professionals by appointment only and offers actual-size samples side by side, allowing for a combined assessment of anti-slip texture, matte finish, and grout color. Our manufacturers from Spain and Portugal supply these samples in actual dimensions for a mood board per zone. For private wellness in a residential project, our application page for living room tiles aligns with the adjacent living space.
