Rectangle Silicone Soap Molds - Set of 2 for 12 Cavities - Mixed Patterns by the Silly Pops
The Silly Pops set of 2 rectangle silicone molds with 12 cavities in mixed patterns for decorative bars.
A bar soap mold shapes individual bars directly, whether through single cavities or a tray of connected wells, so you skip cutting a loaf entirely. This makes it a friendly choice for home soap makers who want uniform bars, clean edges, and a repeatable weight without a cutter. Melt-and-pour beginners especially benefit, since pouring straight into cavities keeps the process simple. When comparing options, check the cavity volume against your recipe, the flexibility of the silicone for easy release, and how well the base sits flat so bars set level. Deeper cavities give a chunkier, hand-feeling bar, while defined edges and a smooth interior surface leave a polished finish that needs little cleanup.

#1Freshware SP-100RD 6-Cavity rectangle premium silicone mold in red, usable for soap bars and resin.
Fit for the job 9/10 · Features and specs 8/10 · Build and materials 8/10 · Value 8/10
- + Premium silicone from a known bakeware brand holds shape well
- + 6-Cavity rectangle layout makes quick uniform bars
- + Doubles as a resin mold, so it has uses beyond soap
- - Red silicone can make judging pale soap colors a little harder
- - Only one mold in the pack, so large sessions need more
#2The Silly Pops set of 2 rectangle silicone molds with 12 cavities in mixed patterns for decorative bars.
Fit for the job 8/10 · Features and specs 8/10 · Build and materials 7/10 · Value 8/10
- + Mixed patterns add decorative texture to bars with no extra effort
- + Set of 2 provides 12 cavities for a medium-size pour
- + Patterned tops make simple melt and pour bars look more polished
- - Patterned cavities can trap air bubbles, so spritz with alcohol

#3POPBLOSSOM 2-pack of 6-cavity oval silicone molds, 12 oval cavities in total. A change from rectangles for makers who want oval bars of handmade soap.
Fit for the job 8/10 · Features and specs 7/10 · Build and materials 7/10 · Value 9/10
- + Each tray is about 11 x 6.25 x 1 inches with cavities near 3.1 x 2.4 x 1 inches, a full-size oval bar.
- + Twelve cavities across two trays fit a melt and pour or cold process batch in one go.
- + Listed as temperature resistant from -40 to 440 F and dishwasher safe for easy cleanup.
- - Cavities are flat-bottomed rather than domed, so the finished bar looks different from a glossy domed oval design.
- - The listing is broad (candy, candles, resin), so details specific to soap, such as cavity volume, are not given.
#4JET LAG 2-pack of large rectangle silicone soap molds. Each cavity measures 3.5 x 2.3 x 1.2 inches and makes a 5 oz bar, a good fit for full-size rectangle soaps.
Fit for the job 8/10 · Features and specs 7/10 · Build and materials 7/10 · Value 8/10
- + The listing gives exact cavity size, 3.5 x 2.3 x 1.2 inches, and a 5 oz bar, which makes batch planning straightforward.
- + Made from food grade silicone, with a description of easy release and smooth corners on the finished soap.
- + Also listed for lotion bars and baking, so the molds stay useful beyond soap.
- - The listing does not state the number of cavities per tray, so the yield per pour is unclear from the text.
- - Silicone trays are flexible and need to sit flat on a tray or board while filled to avoid spills.
#5A 12-Cavity square soap mold marketed as a loaf bar and swirl making tool for handmade square bars.
Fit for the job 8/10 · Features and specs 7/10 · Build and materials 7/10 · Value 8/10
- + 12-Cavity layout makes a full batch of square bars at once
- + No cutting needed, so every bar comes out the same size
- + Square bars stack and package neatly in gift boxes
- - Swirl marketing is a stretch, since small cavities limit swirl designs
- - Measure the cavity size and silicone thickness yourself before ordering
#6WYAHYQ set of three silicone soap molds in round, oval and square shapes, four cavities each. Suits makers who want a few bar shapes from a single purchase.
Fit for the job 8/10 · Features and specs 7/10 · Build and materials 7/10 · Value 8/10
- + Three shapes in one set let you vary the look of a gift collection without buying separate mold packs.
- + The listing states each mold has four cavities sized for full-size bars of soap, wax melts or bath bombs.
- + BPA-free food-grade silicone is rated from -40 F to 446 F, with a non-stick surface and foldable storage.
- - Only four cavities per mold means smaller batches per shape than in 6 or 12 cavity trays.
- - The listing does not give cavity dimensions, so bar weight must be checked before planning a recipe.
#7Lerykin 3-pack of rectangle silicone molds with 6 cavities each, in pink, blue and purple. A bar-soap format for melt and pour or small-batch handmade soap.
Fit for the job 8/10 · Features and specs 6/10 · Build and materials 7/10 · Value 8/10
- + Three molds with six rectangular cavities each give a large number of bars from a single melt and pour session.
- + The listing describes BPA-free, non-stick silicone that pops out when flipped, and states it is dishwasher safe.
- + Rectangle cavities match the classic bar shape, so the finished soaps stack and wrap easily for gifting.
- - The listing does not give cavity dimensions or weight per bar, so bar size has to be checked on the product page.
- - It also advertises chocolate and ice cube uses, so it is a general mold rather than one made only for soap.
#8SJ rounded rectangle soap mold set: two silicone trays with six cavities each. A bar-shaped mold with softened corners for melt and pour or small-batch handmade soap.
Fit for the job 8/10 · Features and specs 6/10 · Build and materials 7/10 · Value 8/10
- + Two trays with six cavities each yield twelve bars per fill, a useful size for a batch.
- + Rounded corners are part of the design, which gives a softer-edged bar than a sharp rectangle.
- + The listing describes food grade silicone that is non-stick, flexible and dishwasher safe.
- - No cavity dimensions or per-bar weight are listed in the main feature bullets, so check the product page for size.
- - The wording is broad (candy, snacks, bath bombs), so it is a general-purpose mold rather than a dedicated soap line.
