A good ceramic soap dish does more than hold a bar of soap. It lets water leave the underside, keeps the bar from sitting in a shallow puddle, and has enough strength to survive being lifted and washed. The form can remain simple: a shallow slab with gently raised edges, supported by feet or ridges and pierced with a few carefully placed holes.
This is a useful beginner project because it introduces several habits that matter in hand building: rolling an even slab, compressing clay, joining parts securely, and drying a small object without rushing it. Work with a clay body and firing range that your studio knows well, and keep the finished dish modest in size. A compact dish is less likely to sag or warp than a broad, thin tray.
Materials and preparation
Gather:
- Stoneware clay
- Two rolling guides of equal height
- Canvas, a cloth, or a lightly textured board
- Needle tool
- Rib or old bank card
- Small hole cutter, metal straw, or similar round tool
- Sponge and a little water
- Slip or scoring tools for joining
- A studio-approved glaze suitable for regular bathroom use
A finished dish around 10 by 14 centimetres is a comfortable starting point, though you can adjust the size for your soap. Leave enough space around the bar for fingers to lift it without scraping the rim.
Choose clay that is still workable but not sticky. If it is very soft, the slab will distort when lifted. If it is already stiff, the edges may crack when you bend or raise them. Wedge the clay according to your studio’s usual practice, then keep the unused portion wrapped so it does not dry while you work.

1. Roll an even slab
Cut or pat out a piece of clay slightly larger than the intended dish. Place it on canvas or another surface that will allow you to lift it without pulling the clay out of shape. Set the rolling guides on either side and roll across them with steady pressure.
Turn the slab once or twice as you work, changing direction rather than repeatedly pressing in one place. The guides should keep the thickness consistent. For a small soap dish, a slab roughly 8 to 10 millimetres thick is a useful starting point; the important point is evenness rather than a particular measurement.
Lift the slab by supporting it with both hands, or slide the canvas beneath it. Do not pick it up from one corner. Uneven handling at this stage can introduce a twist that becomes difficult to correct later.
2. Cut the base and soften the edges
Cut a simple rectangle or oval with a needle tool and a paper template. A rounded rectangle is forgiving: its corners are less likely to catch on cloths or chip during use. Compress the upper and lower surfaces with a rib, drawing it across the clay with light, even strokes.
Compression helps tidy the surface and brings the edges into line, but it will not rescue a slab that has been rolled unevenly. Check the thickness at the corners and along the sides. Trim stray crumbs and smooth the cut edge with a nearly dry finger or a soft sponge.
Avoid making the rim paper-thin. A narrow, slightly softened edge is pleasant to handle and less vulnerable than a sharp, feathered one.
3. Add a raised rim, feet, or drainage ridges
There are several ways to keep the soap above the draining water. The simplest is a pair of low clay ridges running across the dish. Small feet or four low pads work as well, while a raised rim helps contain drips but should not form a sealed basin.
For ridges, roll two narrow coils, flatten them gently, and cut them to fit inside the dish. For feet, use small pieces of clay of equal size. Keep these supports low enough that the soap will not wobble. Three supports can work particularly well because three points establish a stable plane, but four matching feet are straightforward to arrange.
Score and slip every joining surface. Press the pieces into place without squeezing them flat, then blend the inner seam with a finger or rib. The outer seam should be neat but not overworked. Thick attachments and abrupt changes in thickness are more troublesome than a plain, modest support.
Allow the dish to firm slightly before adding the supports if the base is too soft. This makes it easier to work without leaving deep fingerprints or bending the slab.
4. Make the drainage holes
Mark the holes before cutting them. Place them in the low areas between the supports, where water can move away from the bar. Three to five holes are usually enough for a small dish; the precise number matters less than keeping them clear of corners, rims, and attachment seams.
Use a small round cutter, metal straw, or similar tool. Press straight down and twist gently rather than levering the tool sideways. Sideways pressure can stretch the hole and create a weak, thin edge. Remove the clay plug from below with the needle tool.
Keep a generous margin between a hole and the outer edge. Holes too close to corners can leave very little clay at the point most likely to be knocked. They also make the slab more prone to distortion while drying. If a hole looks ragged, refine it while the clay is still leather-soft with a damp tool or small sponge.
Do not place holes directly under a foot or ridge. The support should remain continuous and firmly attached, while the openings should have a clear path for water.

5. Refine the form at leather-hard stage
Let the dish rest until it reaches a leather-hard firmness: it should hold its shape when lifted, but a tool should still mark the clay. Check the rim for waviness and the feet for equal height. Set the dish on a flat surface and press very gently on opposite corners. If it rocks, adjust the lowest support or carefully refine the base.
Soften all exposed edges. A slightly rounded rim is easier to clean and less likely to chip than a sharp one. Clear crumbs from the drainage holes and inspect the underside for ridges of clay that could scratch a counter.
This is also the time to add a small maker’s mark or a restrained surface detail. Keep decoration shallow and avoid deep cuts through the base. The dish has a practical job, and a calm surface will be easier to wipe clean.
6. Dry it slowly and evenly
Drying is where many small slabs fail. Cover the dish loosely with plastic so moisture leaves gradually. Keep it on a flat, absorbent board and turn it occasionally if your studio practice allows, taking care not to lift it by the rim or feet.
The base, raised supports, and rim do not always dry at the same rate. A slow, even drying period gives these parts time to contract together. Do not put the dish in direct sun, near a heater, or in a strong draught. Wait until it is completely dry before bisque firing; clay that still feels cool or damp may not be ready.
Follow your studio’s firing schedule and kiln guidance. Clay bodies differ, and a dish should be fired to the range recommended for that clay rather than treated as a generic recipe.
7. Glaze with the bathroom in mind
After bisque firing, brush or dip the dish in a glaze approved by your studio for the clay body and firing temperature. A smooth, well-fired surface is easier to rinse than a rough or heavily textured one. Keep glaze out of the drainage holes and off the underside of the feet, unless your studio specifically permits otherwise.
Glaze can pool in holes and close them, or collect beneath the dish and fuse it to a kiln shelf. Wipe the foot ring and check every opening before the final firing. If you want the natural clay to remain visible underneath, leave a clean, even margin rather than wiping glaze away in a hurried patch.
A glossy interior is not essential, but a surface with deep crawling, pinholes, or rough patches will be harder to keep clean. When in doubt, choose a dependable studio glaze and test it on a small tile or spare piece made from the same clay.

Useful mistakes to avoid
Making the slab too thin
A thin base may look delicate, but it gives little room for holes and supports. It is also more likely to warp as it dries. Begin with a modestly thick, even slab and refine the form rather than shaving it excessively.
Cutting holes at the corners
Corners already concentrate stress and are vulnerable to knocks. Keep openings in the central drainage area, with solid clay between each hole and the rim.
Adding supports without scoring and slip
A foot that merely sits on the base may detach during drying or firing. Prepare both surfaces, join them firmly, and blend the seam without creating a bulky lump.
Drying only the top
Leaving the dish uncovered can let the rim become hard while the underside remains damp. Slow the whole process with loose plastic and patience.
Glazing the underside carelessly
Glaze on the foot ring may stick to the kiln shelf, while glaze in the holes defeats the purpose of the design. Clean these areas thoroughly before firing.
Using the finished dish
Place the dish where water can drain freely and rinse it from time to time. If soap residue gathers beneath the bar, clear the holes and wash the surface rather than adding more glaze or sealing the openings. A well-made dish should let the bar dry between uses, but it still benefits from ordinary cleaning.
The best version is usually the quietest one: an even slab, a stable lift beneath the soap, open drainage, and edges that feel natural in the hand. Once these proportions are familiar, the same method can be adapted for a toothbrush rest, a small sponge tray, or other useful household pieces.
