If you’re torn between the Rabbitgoo Rainbow Window Privacy Film, the ALIUNI Stained Glass Film, and the DOWELL Stained Glass Film, you’re looking at three very similar static-cling options. All three are 17.5″ x 78.7″ and use the same no-glue installation method, but they differ in UV protection and color effects.
This comparison is for anyone who wants bathroom privacy without losing natural light. The key trade-off is UV blocking strength versus the specific rainbow effect you prefer. I’ve dug through the specs so you can pick the right one for your space.

Individual Product Breakdown
I spent time digging through the specs, customer feedback, and installation details for each of these rainbow privacy films. Here’s my honest take on how each one performs for a bathroom window.

The Rabbitgoo is the most proven option here with nearly 80,000 ratings and over 10,000 units bought in the past month — that tells you a lot about reliability. I like that it blocks 96% of UV rays while offering 60% privacy protection, which is decent for a bathroom. The 3D laser design creates those rainbow glows only when sunlight hits it, so it looks clear when overcast. It’s priced lower per square foot than the others, making it the best value for most people.
✅ Pros
- Blocks 96% of UV rays effectively
- Huge track record with 79,747 ratings
- 2-year manufacturer warranty included
- Reusable static cling with no glue
❌ Cons
- Only 60% privacy protection, not fully opaque
- Rainbow effect requires direct sunlight

The ALIUNI stands out because it blocks 99% of harmful UV rays — the highest of the three — while also reducing heat and glare by 50%. That makes it the best choice if your bathroom gets intense afternoon sun. I appreciate that it’s marketed as pet-friendly and eco-friendly, which is a nice touch for families. The 3D rainbow effect changes with weather conditions, so you get a dynamic look. Just know it has far fewer reviews than the Rabbitgoo, so the long-term track record isn’t as established.
✅ Pros
- Blocks 99% of UV rays — best of the three
- Reduces heat and glare by 50%
- Non-toxic and safe for pets
- Works on glass, plastic, and other smooth surfaces
❌ Cons
- Only 1,050 ratings — less proven than Rabbitgoo
- Slightly higher per-square-foot cost
DOWELL Stained Glass Window Privacy Film
17.5″ x 78.7″ | Static Cling | Blocks 84% UVA / 99% UVB | 172 ratings
- Enjoy natural light in privacy: Our semi-privacy film diffuses incoming...
- Lively Rainbow-Themed Decor: Our stained glass window film features delicate...
- UV Protection Barrier: Our window cling blocks up to 84% of UVA and 99% of UVB...
The DOWELL is the newer option with just 172 ratings, but it’s already picked up 300+ purchases in the past month. I like that it blocks 84% of UVA and 99% of UVB rays specifically — that’s a more detailed breakdown than the others give. The semi-privacy design diffuses sunlight into a soft glow while still letting daylight through, which is exactly what you want in a bathroom. It’s priced the same as the ALIUNI but has fewer reviews, so you’re taking a slight chance on a newer product.
✅ Pros
- Blocks 99% of UVB and 84% of UVA rays
- Reduces glare and heat for comfort
- No glue — easy to install and remove
- Versatile for living rooms, kitchens, and offices
❌ Cons
- Only 172 ratings — unproven long-term durability
- No warranty information listed
Which One Should You Buy?
Honestly, all three of these rainbow films will get the job done for a bathroom window, but the right pick depends on what matters most to you. Let me break down who each one is actually for.
Rabbitgoo Rainbow Window Privacy Film is right for you if…
- You want the most proven product with 79,747 ratings and a 2-year warranty backing it up
- You’re on a tighter budget and want the lowest per-square-foot cost of the three
- You’re renting and need a reusable, non-adhesive film that won’t damage the glass
ALIUNI Stained Glass Window Privacy Film is right for you if…
- Your bathroom gets intense sun and you want maximum UV protection at 99%
- You want to cut heat and glare by 50% to keep the room cooler
- You have pets and want a non-toxic, pet-friendly film that’s safe around them
DOWELL Stained Glass Window Privacy Film is right for you if…
- You want specific UVB protection at 99% while still letting soft daylight through
- You need a versatile film that works in living rooms, kitchens, offices, or garages too
- You’re okay trying a newer product that’s already moving 300+ units per month
❌ Who Should Skip All of These?
If you need total privacy where nobody can see shapes or movement through the glass, a static cling rainbow film isn’t going to cut it — these all offer semi-privacy at best. You’d be better off with a frosted or opaque privacy film, or even a traditional curtain or blind for complete coverage.
For the most common bathroom scenario, my pick is the Rabbitgoo. It has the largest track record, the lowest price per square foot, and the 2-year warranty gives you peace of mind that the other two don’t offer.
Frequently Asked Questions
Which rainbow window film blocks more UV: Rabbitgoo or ALIUNI?
ALIUNI is the clear winner here, blocking 99% of harmful UV rays compared to Rabbitgoo’s 96%. That 3% difference might not sound like much, but if your bathroom window gets direct sunlight for hours, it adds up over time. The ALIUNI also reduces heat and glare by 50%, which makes it the better choice for sun-drenched rooms. I’d pick ALIUNI if UV protection is your top priority.
Is the Rabbitgoo worth paying more for than the DOWELL?
Actually, the Rabbitgoo is the cheaper option per square foot at check current price on Amazon compared to DOWELL’s check current price on Amazon. So you’re not paying more — you’re paying less for a product with 79,747 ratings and a 2-year warranty. The DOWELL only has 172 ratings and no listed warranty, so the Rabbitgoo gives you more confidence for less money. That said, the DOWELL does block 99% of UVB rays specifically, which is slightly better than Rabbitgoo’s overall 96% UV claim.
Which film is best for a bathroom that gets a lot of moisture and steam?
All three use the same static cling installation method, so they should hold up similarly in a steamy bathroom. The key is proper installation — you need to spray water on both the glass and the film’s back, then squeegee out the bubbles. I’d lean toward the Rabbitgoo here because it has the longest track record with nearly 80,000 ratings, meaning any moisture issues would have surfaced by now. The DOWELL is too new at 172 ratings to know how it handles long-term bathroom humidity.
Can I reuse these films if I move to a new apartment?
Yes, all three are designed to be reusable since they’re non-adhesive static cling films. The Rabbitgoo specifically mentions it can be easily removed and reused multiple times, which is ideal for renters. The ALIUNI and DOWELL also claim no residue upon removal, so you should be able to peel them off and reapply elsewhere. Just be gentle when removing and store them flat to avoid creases.
Which film provides better privacy: ALIUNI or DOWELL?
Neither lists a specific privacy percentage, so honestly, they’re likely very similar in that regard. The Rabbitgoo is the only one that gives a concrete number — 60% privacy protection. That means all three will obscure direct views but won’t completely hide shapes or movement. If full privacy is critical, you’d need a frosted film or curtains instead of any of these rainbow options.
Is the DOWELL worth considering over the ALIUNI if they cost the same?
I’d go with the ALIUNI. They’re both priced at check current price on Amazon per square foot, but the ALIUNI has 1,050 ratings versus DOWELL’s 172, and it blocks 99% of UV rays while reducing heat and glare by 50%. The DOWELL does offer a more detailed UV breakdown (84% UVA and 99% UVB), but the ALIUNI’s broader track record and stronger overall UV claim make it the safer bet. The DOWELL only makes sense if you specifically want that UVA/UVB split.
My Final Verdict
After comparing all three rainbow window films, the Rabbitgoo is my clear overall winner. It blocks 96% of UV rays, offers 60% privacy protection, and comes with a 2-year warranty — all at the lowest per-square-foot price with nearly 80,000 ratings backing it up. The ALIUNI is the runner-up, best for anyone who needs maximum UV blocking at 99% and heat reduction of 50% in a sun-drenched bathroom.
If you’re still on the fence, think about what matters more: proven reliability or maximum UV protection. The Rabbitgoo gives you decades of customer feedback and a warranty, while the ALIUNI edges it out slightly on UV specs. For most bathrooms, the Rabbitgoo’s combination of price, track record, and protection makes it the safest choice you can make.
