So glad I tried Bath Diamond!

Has anyone else tried the Romantic Bath Set? I'm always a bit hesitant with new brands because my skin is super sensitive, and I've had issues with things from Lush and Bath and Body Works before. But Bath Diamond's ingredients looked really good, so I gave it a shot. Everything arrived pretty quickly, and the packaging was lovely. The bath bombs dissolved beautifully without leaving any weird residue or making my skin itchy. It was a really nice experience overall.

Always great bath bombs

This was my third order from Bath Diamond, and they delivered again. I got the Bioluminescent Bath Bomb this time. Just like my previous purchases, it had that cool glow and left my skin feeling soft. Consistency is key for me, and they've always been reliable. That's why I keep coming back.

Great value on the bundle

I was looking for some new bath products and stumbled upon Bath Diamond. I picked up the Rose Bathdiamond Bundle because it seemed like the best deal. For what I paid, getting both a bioluminescent bath bomb and soaking salts felt like a real win. The free shipping on orders over $50 helped too. It was worth it, especially as a first-time buyer wanting to try things out without breaking the bank.

Relaxing, but packaging could improve

I tried the Lavender Bathdiamond Bundle, and the bath bomb was really soothing, exactly what I needed after a long week. The bioluminescence was a unique touch that made the bath special. My only small gripe was the outer box was a bit dented when it arrived, though the products inside were fine. Shipping took 6 days to get to my place in Texas. Overall, a nice experience for the price, but they could use sturdier packaging for transit.

Soaking Salts Gift Set is amazing

I got the Soaking Salts Gift Set last week, and it's incredible! The scents are so relaxing, and the salts dissolved perfectly. It made my bath feel like a spa experience. I'm already planning my next order, probably a Rose Bathdiamond Bundle. Definitely telling all my friends about this!

Hey, thinking of trying these glowy bath bombs. Do they actually glow a lot or is it just a tiny bit? And how long does it last in the tub?

E Emma 2 months ago
Oh, they totally glow! Not like blinding, but it's really cool, especially if you dim the lights. Mine lasted for the whole bath, maybe 30-40 minutes easy.

Yeah, it's pretty impressive. It's not like LED bright but more of a soft, kinda magical glow. It definitely keeps going for the duration of a normal bath. I'd say maybe an hour at most before it fades out completely.

Has anyone used their first order discount? Is it a good amount off or just a tiny bit?

A Andre F. 2 months ago
Yeah, I got 10% off my first order when I signed up for their email list. It's not massive but every bit helps!

It's typically 10-15% off, not bad for a first-time purchase. Sometimes they have better deals with bundles though, so check those too.

What's the deal with returns if I buy a bundle and don't like one of the items? Can I return just part of it?

J Julia N. 1 month ago
I've only returned a whole order, which was easy. I'm not sure about partial returns for bundles, you might have to send back the whole thing. Better to check their policy on the site.

i think generally with bundles you gotta return the whole thing to get a refund. not super common to just return one piece of a set, afaik.

Does anyone know how long shipping takes to, say, California? Trying to get one for a gift next week.

D David Osei 1 month ago
I'm in SoCal and my last order got to me in about 4-5 business days. Might be cutting it close for 'next week' depending on when you order.

From what I've seen, it usually ships within a couple of days and then takes another 3-5 days for delivery. So if you order by Monday, it *might* get there by Friday, but no guarantees.

Is Bath Diamond better than Lush or other popular brands? What makes it special besides the glow?

D Dana 1 month ago
Honestly, the glow is the biggest thing that sets them apart. Lush has cool scents, but Bath Diamond's experience feels more luxurious and spa-like, especially with the bioluminescence. It's a different vibe.

It's a totally different experience than Lush. Lush is more about fun colors and strong scents. Bath Diamond is more about relaxation and that unique glow. I think the ingredients feel higher quality too, less artificial than some other brands.
