How does the Tetravan In-Floor Shower Pan work?

The pan recesses flush into the van floor, sitting just over 1" below floor level. A magnetic curtain attaches directly to the pan edge for showering, and the pan is walked over the rest of the day — zero headroom or floor space lost.

What are the dimensions of the Tetravan In-Floor Shower Pan?

Overall 30" × 24" with a 28" × 22" recessed interior, 1.31" deep, 1" flange, 2.01" center drain opening, and 24.6 lb weight. Minimum 1.3" of subfloor depth is required.

Which shower curtain works with the In-Floor Shower Pan?

The Tetravan Universal Shower Curtain: 3/8" magnets seal to the inside pan edges, zippered front entry, 30"+ width at shoulder height, 71" tall, extendable to roof height with 6" extenders.

Where can the drain be positioned on the In-Floor Shower Pan?

Center drain is standard with a cross-break bottom directing water to it; additional drain positions are available. A 1-1/2" threaded straight drain fitting is included.

How is the In-Floor Shower Pan installed?

Cut the floor opening, apply adhesive to the underside of the flange, secure with at least 1" countersunk screws through the flange into the subfloor, and route the drain to a grey tank.

Should I choose the In-Floor Shower Pan or the Tetravan Folding Shower?

The In-Floor Pan suits builds with a dedicated shower spot — permanent, low-profile, full headroom. The Folding Shower suits builds where floor space is precious, stowing into 3.5" of wall depth.

Does the In-Floor Shower Pan ship internationally?

It ships to the contiguous US, Canada, and select European countries. Other countries can email contact@pundmann.de for a shipping quote. International orders may incur customs duties.

Q: Does the In-Floor Shower Pan work in a Ram ProMaster?

Yes, but ProMasters sit stock-sloped nose-down, so a leveling kit is required for proper drainage. Sprinters and Transits install without modification when level.

About the Product

The Tetravan In-Floor Shower Pan recesses flush into your van floor — out of the way and hidden in plain sight until you need it. A cross break in the bottom directs water to the center drain, and the magnetic brushed stainless steel construction means your shower curtain seals directly to the pan edge without clips or tracks.

Frequently Asked Questions

How does an in-floor shower pan work?

The pan recesses flush into your van floor, sitting just over 1" below floor level — invisible underfoot until shower time. Attach the magnetic curtain to the pan edge, shower, then walk right over it the rest of the day. You lose zero headroom and zero floor space.

What are the dimensions and cutout requirements?

Overall 30" × 24" with a 28" × 22" recessed interior, 1.31" deep, 1" flange, and a 2.01" center drain opening. You need a minimum 1.3" of subfloor depth. Weight is 24.6 lb.

What is it made of?

Brushed 2205 duplex stainless steel — anti-corrosive and magnetic, so shower curtain magnets seal directly to the pan edge with no clips, tracks, or hardware.

Which shower curtain works with it?

The Tetravan Universal Shower Curtain: 3/8" magnets seal to the inside pan edges, zippered front entry, widens to 30"+ at shoulder height, and stands 71" tall. Six-inch extenders can take it to roof height.

Where can the drain go?

Center drain is standard, with a cross-break bottom that directs water to it. Additional drain positions are available — including corner-drain configurations — if your build routes plumbing differently. A 1-1/2" threaded straight drain fitting is included.

Does it work in a ProMaster?

Yes, with one caveat: ProMasters sit stock-sloped nose-down, so a leveling kit is required for proper drainage. Sprinters and Transits install without modification as long as the van is level.

How is it installed?

Cut the floor opening, apply adhesive to the underside of the flange, and secure with at least 1" countersunk screws through the flange into the subfloor. Route the drain to your grey tank.

In-floor pan vs. Folding Shower — which should I choose?

The In-Floor Pan is for builds with a dedicated shower spot: permanent, low-profile, full headroom. The Folding Shower is for builds where floor space is precious — it stows into 3.5" of wall depth. Many builders use the pan in the entryway and rely on the same water system for both.

Do you ship internationally?
