Adding a bathroom Porthole window to a 320s ?

Member Posts: 258
Hi all,
We are in the middle of a brand new 2019 320s purchase and hope to pick it up this week . (Cant Wait !
)
It was tricky to find the color scheme we wanted as there are not many 2019's left . MUCH prefer the 2019 interior over the 2020 (but thats a whole other topic !)
Anyway, found the exact one we want with all kinds of great options and the right color combo we were looking for, from a great dealer close by (well about 3 hours!)
The only option it does not have is the bathroom porthole window that we would have liked .
Is it possible to add the port hole window ?
Assuming we could get one from Nucamp, and find out the exact mounting location measurements the factory uses , I dont see why it cant be done ???
Anyone ever add one of these ?
How about any voiding of warranty stuff ?
Thanks for any opinions !

This was discussed at the 2019 T@Bazona by a nuCamp representative. The factory installs the bath portal in the exact position of the door mounted one, They also stated that there is nothing in the bath wall that would interfere with installing the portal window. No wires, framing, etc, just foam sandwiched wall.T@B 320 manuals and electrical drawings

@B0atguy, you may want to try using it a bit before you go to the trouble and expense. We have the bathroom window (not intentionally, just was on the unit we bought off the dealer lot). I have to say, while I initially thought it would be great to have to let even more light in, we actually have never opened the shade! So you may find you don’t really miss it.
We all have different preferences, but just wanted you to know that if you otherwise found the perfect unit for you, go for it!2018 T@B CS-S Towed by 2015 Subaru Outback 2.5i in the wilds of Minnesota -

The bathroom window was one of the things I had to give up when an unexpected financial hit pushed me from the unit of my dreams to a less expensive one. When I really looked at the positioning of that window, I realized I’d leave it closed all the time anyway. The only time I wish it was there is when I occasionally notice the lack of symmetry on the outside. Never when I’m inside.
Live without for a while, you can have one added at üCamp in a year or so if you want!2019 320s BD Lite, white with blue (“Haven”)

Thanks for the replies . Good to know it can be added, but perhaps we will roll with it first and see if we would rather do without it ! Good call !

That window wasn't an option when we got our 2015, so we don't miss it. We use our bathroom for showers and the other things, but we certainly don't hang out in there enough to need a window.

LOL, we were mostly thinking of the extra lighting it provided . I guess if it was a rainy day I could just sit in the bathroom all day and look out the window though ..........db_cooper said:That window wasn't an option when we got our 2015, so we don't miss it.

We picked up the porthole window while at the 2018 rally. It can be mounted most anywhere on the wall. We determined where we wanted it from the inside. It doesn’t have to be in the same location as the door side in my opinion. The only thing is getting up the courage to cut a 12” hole in the side of your trailer. We like the light and would do it again.

I just picked up my T@B 320 S a week ago. It was ordered in March as a 2019. Because it was Mfg in May, it came out as a 2020, with the new (dark wood) color scheme - and a porthole in the bath. I assumed it was a standard item.

I purchased a bathroom porthole window kit from Elsie, late last year, but only just getting around to installing it. I see no problem in cutting a hole in the Adzel, but was surprised to find the actual outer window has no screws or clamping mechanism and is affixed to the outside only by the adhesive/caulk. I was wondering if @Dalehelman has any tips on ensuring the window is properly adhered to the outside. Many thanks!Dalehelman said:We picked up the porthole window while at the 2018 rally.

@teztab
Clean surface with alcohol. You really only get one shot. Once the tape makes contact do not lift or try to reposition. Press firmly. That’s it. Good luck.- Hash T@B Fun

Many thanks @Dalehelman ! So did your kit come with adhesive tape or is that something you purchased separately. My kit did not come with tape. Would that be 3M adhesive tape? Thanks again...

LOL fun thread to read

One of the things I liked about doing a Factory Order purchase was being able Not to get that window. Seems my local dealer likes to order units fully optioned out . . . . . .B0atguy said:. . . only option it does not have is the bathroom porthole window that we would have liked .'18 320 S, pitched axle, 3020HE; PNW basedTV: '17 Colorado V6 Z71 4x4, Tow Package, GM Brake Controller

@teztab
3M 1/4” red backed tape is what came with ours. I did have to apply it myself. You can find it at Walmart and most auto parts stores. An even better choice is VERY HIGH BOND 3M tape. Search VHB Scotch mounting tape on Amazon.

I know it well, @Dalehelman. Many thanks for the clarification!

Being an ex-sailboater I guess I have a bias. If I didn't have a window in my 320s and knowing what I know now, I would consider this marine grade opening porthole instead of the T@B stock round window.
Aside from the obvious reason for having a window that opens in the bathroom, it is also nice to have the extra ventilation. Taking a shower, shampooing your hair or just drying some towels or swimming gear. If I could find one the correct size for the existing window opening or even a little larger I would change mine. Here is the link if you're interested.

Just one more thing, the description says hull (wall panel) thickness 1/8" to 7/8". I'm not sure the thickness of the Azdel wall panel but if it's over 7/8", this unit won't work.newell said:

Well , after getting some use out of the T@B without the bathroom porthole window , I think we are going to leave it be . We dont need the window, and it will let in a bunch more light at the early hours of the morning (When we want to sleep in ! lol) .
I kind of like the symmetrical look of 320 with the bathroom porthole window though . That side looks a little plain without the window .........2023 Ford F150 Sport 3.5 Ecoboost

Much easier to wipe down the wall after a shower without the window.2019 TaB 320 S Boondock Edge

Just installed a bathroom window in our 320. Job was relatively easy and took less than an hour. I spent most of that time measuring and mapping where to cut the hole and exactly where the glass should adher. As @Dalehelman mentioned, the tough part is plucking up the courage to start cutting!
While I understand the factory positions the bathroom window to mirror the door porthole, I positioned ours at about the same height, but at the mid pojnt between the window and end trim. It looks great on the outside and, I feel, adds natural light and a greater feeling of spaceousness on the inside. I still have the rotating blind to fit, but rather than adhering that permanently, I plan to use small velcro pads so it can be removed for wiping and cleaning. Feeling very pleased with this easy upgrade!

That came out great ! Love the centered location .
Question - How much did the window cost ? Was it direct from nuCamp ? (not sure if nuCamp manufactures these windows or another manufacturer ???)
Still thinking I may add this to our 320 .........

He mentioned earlier in the thread that it was direct from nuCamp, but late last year before the parts change went into effect. Now it would need to go through a dealer, likely with some markup.B0atguy said:

I purchased the window last fall, when it was still possible to order directly from Elsie at Nu Camp. I just checked what I paid and the window, including the inner shroud, was $94. I also purchased the little rotating blind and that was $33. Obviously, there was also some shipping cost.
This is something I've been wanting to do since purchasing our 2018 T@b. The dealer had pre-ordered it so there was no opportunity to specify the extra window. The job is relatively easy if you take care and have the confidence to do it. Measure/check, messure/check, then measure and check again!😀 -
FWIW - For those considering this modification. The passenger side porthole on my DM T@B is much larger than the door window. The transparent area on the door is ~10 inches verses ~13 inches on the opposite wall. I think this may be the size used on the 400. It may be possible to fit the larger window if desired.Nice job teztab

Interesting - I was not aware there were other diameters available. I ordered a 320 bathroom porthole window and received what is the same as the door window. I'm very happy with the size as it is though....rfuss928 said:FWIW - For those considering this modification. The passenger side porthole on my DM T@B is much larger than the door window.
