FUNDO PRIMO BASE

The original Wedi Fundo Shower Base. These robust, pre-sloped, waterproof shower floor bases come with a Wedi Click and Seal Drain Unit. You can select one of the square Wedi Premium Drain Cover options to fit the preferred design.

The Wedi Fundo Primo Shower System, like all Wedi Shower Systems, offers full warranty coverage thanks to its complete and natural waterproof core and range of specially engineered components. The Wedi Fundo Primo is internally waterproof due to its Wedi XPS foam‘s closed cell structure and naturally protects against mold or mildew like every Wedi XPS foam-based product.

It is fast and clean to cut to fit custom designs while prefabrication reduces installation time significantly. The base features a strong and pre-sloped surface, allowing for tiling immediately whether you choose a mosaic or large format tiles. The Wedi Fundo Primo is primarily made to work in shower designs including a Wedi curb.

Pre-sloped extension panels are available so that no limit exists for creating any size or shape for custom shower designs. The Wedi Fundo Primo is insulating, creating a thermal barrier that can prevent cold from transferring through the tiled surface, and makes floor heating systems more efficient. It also has outstanding moisture and water exposure control compared to traditional mortar bed installations or other currently known methods for building showers, including the use of sheet or liquid waterproofing membranes which can be very thin and vulnerable or they may offer water absorption into thin-set bonded seam areas.

Wedi Fundo Primo Shower Base Features:

  • Multiple base sizes and extensions available - all customizable on site if needed.
  • Square and rectangular base options with center or off-center point drain locations.
  • Slope design allows for use of small or large format tiles when cut along slope lines.
  • Installed over various types of subfloors.

Wedi Click and Seal Drain Unit Features:

  • Commercial grade, solid drain body
  • Fundo Click and Seal Drain fits all Fundo Shower Bases
  • Drain Assembly included with every Fundo shower base or kit
  • Drain cover can move both vertically and laterally to accommodate any size of tile
  • Drain cover can be selected a la carte, but standard cover remains included with Kits
  • Drain is equipped with extra weep holes for faster draining of water from thinset mortar layer
  • Hair strainer now included in the drain assembly
  • Fast, clean, and simple installation
  • No plumbing license, glue, or sealant needed
  • "Click" sound as checkpoint marks visible from the top view into the drain confirm the drain has properly sealed to Wedi Base.
  • Seals to ABS, PVC, or cast iron waste pipe- even on drain/floor pipes up to 5° out of plumb
  • A special kit is available to seal to copper pipe
  • Can be cleanly and safely disassembled and reassembled, if plumbing needs to be replaced

Note: The Wedi Fundo Click and Seal Height Adjustment Kit is sold separately. The Drain Cover Exention only works for Wedi’s finished surface drain covers, but not with Wedi’s tileable covers due to their special water drainage design.

Here is how you select the right shower base size to fit the job in most cases:

Determine the distance between the center of the 2-inch pipe in the subfloor to all framed walls and where you plan to have the inside of a Wedi Curb (as if it were another framed wall). Next, take note of the longest dimension of the two distances measured along each axis (east/west and north/south.)

You will need to select a shower base that covers twice the length of the longest dimensions along each axis. This will ensure that the shower base will cover the entire shower area and, if needed, can be trimmed on-site to position the integrated wedi drain over the 2-inch waste pipe in the subfloor.

This method of calculating the correct shower base works for square and rectangular spaces with a mostly centered drain location. Where drains are very close to a wall, one of our off-center drain bases should be used if possible. Refer to the Wedi Technical Drawings section to select the correct base that covers your shower dimensions, and will properly align the integrated Wedi drain with the floor drain pipe.

Customer Questions
In the picture I see a diamond shaped basin however, all the diagram pictures are square or rectangle. Is there a specific diamond basin?
There are no currently available diamond-shaped bases. The image was provided by wedi and is a few years old.
How durable are these pans. I noticed you can dent them just by kneeling on them. Will they dent after tile is installed over pan?
Once you thinset and tile these are extremely durable and one of the best waterproofing products on the market.
I’m planning a 36” x 42” shower. Can the 36 x 48 base be shortened 3” on each end?
Yes, you will want to cut on both sides to maintain center drain. Make sure you reapply the lip on the cuts. The wedi video at the bottom of the product page will show you how to do it.
We have a 30 inch x 5 ft shower/tub enclosure that we are going to tear out and tile. Does the wedi system have a 2.5 x 5 ft with offset drain? Thanks
They don't make that particular size but you can use the 36 .in x 72 .in offset drain (073735521) and cut it to size, 3 inches from each side and 12 inches from the length opposite the drain side to maintain the offset drain. Be sure to add back the lip on the cut sides, the wedi video will show you how to do that.
What is the minimum distance from drain to edge? Can these be trimmed to accommodate a drain that is not centered?
Yes these bases can be trimmed more on one side than another to fit a drain that is off center. On a couple of the sizes there is already an offset option. The slope is the same all the way to the drain so there really is not a minimum required to be left, although you would not want it to be less than the cutout in the substrate for the drain assembly. Please give us a call to let us know what your plan is and we can recommend the right size base to fit your needs. Also see the video on the product page to show you how to cut the base and reapply the lip on the cut edges.
I’m planning an 84” x 67” shower. I see wedi makes an 84” x 60” shower base. Can I add a 7” extender to the short side? If so, which one?
Yes, You will need the 72 .in x 12 .in Wedi shower base extension 73783523, and cut it to your needed size. These follow and extend the slope of the wedi shower bases. Make sure to cut the lip into the extension after you cut to size and keep in mind where you want the drain, The base can be cut to fit as well. We are available for project help if you need, give us a call at 800-938-7925.
Can you add a seat (to be tiled) on top of a wedi pan? I am thinking of the 36x72 pan with offset drain in place of an existing bathtub.
Yes, the wedi seats are designed to be mounted on top of the wedi pans. You do also have the option of a suspended wedi corner seat that is wall mounted.
Can I order directly from you
Yes you can order over the phone or online, for delivery or pick-up at our Georgetown Seattle Store. (800) 938-7925
Can I have a pan made that meets my specific measurements? I have a space that is 63" by 65" .
Apologies for the delay wanted to double check with wedi rep. Wedi does not make custom shower bases. What you would need to do is purchase a 60" x 72" base and a 12" x 72" Extension and cut each down to make your 63" x 63" base. When you cut the base and extension make sure to cut in the bevel. Please contact us if you have any further questions. (800) 938-7925
We want to install a curbless shower and we have a 36” x 72” space, but only 3/4” depth. Do you have a configuration that would work for us?
You could go with the wedi Fundo Ligno 073732016 36" x 60" x 3/4" Pan with the 60" x 12" - US3000035 Fundo Ligno Base Extension to get you to the 72" length.
Can you install the wedi fundo base over a concrete floor? Also, how thick is the base?
Yes wedi bases will install on a concrete substrate. Depends on which one you purchase for the thickness. The technical drawings are available for each base on the product page, there you will see the base thickness at the outside edge and other key measurements.
I am building a custom shower, my rough opening is 79&3/4 inch by 50 inch. Center of drain is 19 &1/4 from one side by 25 inches from one end. Do you have a base or an idea of how I can make one work for me
The 84 x 60 wedi fundo primo shower pan would most likely do the job. It depends how far down the drain is on the 79-3/4" length. If it is about half way down the 79-3/4 length or within 2" of that, you could you this pan and cut it to fit. From your description it sounds like the drain is just slightly off center.  
Broken link. (073735526 60" x 72" w/offset drain) is not working
We check the page and it is working this morning. If the click on the dot (button) next to the title of the size you want, then scroll to the bottom of the page and select add to cart. The product will add to the cart. Also checked in the description and the link for a down load of the item specs works as well. Please let us know if you are still having issues.
