Best Soap Making Equipment for Small Businesses Scaling to Production
Short answer: The best soap making equipment for a small business that plans to grow is a heated 304 stainless soap tank sized to your largest batch with room to grow, plus mixing, pouring and filling equipment added as volume rises. WaxMelters' PRIMO Soap Production Tanks start at the PRIMO 3 (3.5 gal, $1,395) and PRIMO 7 (7 gal, $1,675) and run to 7,979 gal, for oils, fats, tallow, butters, glycerin and soap bases. Add a PRIMO heated pot tipper (from $2,895) to heat, mix and pour in one vessel, and an EZ-1 ($3,450) or AutoShot ($8,495) when hand pouring limits output.
How to size a soap tank (WaxMelters method)
- Largest working batch in gallons: the actual production gallons, not a tank label.
- Add headspace: 20% is the starting planning value; mixing, foaming or ingredient additions may need more.
- Add growth: 50% is the planning value.
Worked example: a 10 gal working batch × 1.20 = 12 gal, which points to the PRIMO 15 (15 gal). With 50% growth, 10 × 1.5 × 1.2 = 18 gal, which points to the PRIMO 25 (26 gal). Confirm with the soap production tank sizing guide.

Take your largest working batch in gallons, add 20% headspace and 50% for growth. A 10 gal batch points to the PRIMO 15 today and the PRIMO 25 with growth.
Can I melt melt-and-pour soap base in a PRIMO tank?
Yes. PRIMO Soap Production Tanks are listed for oils, fats, tallow, butters, glycerin and soap bases.
How do I mix soap in the tank?
A stainless hinged lid with a lid-mounted agitator and mixing blade is an option on the soap tanks, and PRIMO heated pot tippers can be configured to heat, mix and pour in one vessel.
How do I move from hand pouring to production filling?
Add an EZ-1 ($3,450) for operator-controlled heated dispensing, an AutoShot ($8,495) for automated measured fills, or EZ-T (from $2,995) for heated transfer between vessels.
What voltage do soap tanks use?
110–120 V is standard from the PRIMO 3 through the PRIMO 150 at standard temperature; the PRIMO 200 to 500 are 220–240 V.
