Good product, shipping could improve

I bought the Rose Bathdiamond Bundle and generally, I'm pretty happy with it. The bioluminescent effect was really unique and made my bath feel special, just like they advertised. It was a nice, relaxing experience. However, the shipping took about 8 days to get to me in California, which felt a bit long for an online order these days. Customer service was responsive when I asked about the tracking, so that was good. Overall, the value for the unique product is there, but faster shipping would make it even better for future purchases.

Great value for a splurge

I was looking for something special for my wife's birthday but also wanted to save a bit. I got the Luminescent Bath Products set during a buy one get one free soaking salts deal, which made it a much better value. The products themselves were really nice and she loved the glow. It felt like a good splurge without breaking the bank, especially with the extra salts. Definitely worth the purchase for the experience.

Consistent quality, always a good gift

This isn't my first time ordering from Bath Diamond. I've bought their bioluminescent bath bombs several times now, mostly for gifts, and also picked up some Jasmine 19 Soaking Salts for myself this time. Their quality is always consistent; the products arrive well-packaged, and the bath bombs always deliver on the glowing effect. My previous orders were just as good. It's why I keep coming back for special occasions. They're reliable, and the unique aspect makes them stand out from other bath brands.

Nice bath bomb, slow delivery

Ordered a Bioluminescent Bath Bomb. Product was good, created a cool glow. Shipping took a week, which was a bit slow. Satisfied with the item, just wish it arrived faster.

Fun bath experience

So I tried one of their Light Infused Bath Bombs. It was pretty neat, made the water glow all blue and stuff. Felt really relaxing after a long day, you know? It's not like a regular bath bomb; this one actually lights up. Came pretty quick too, like 5 days to reach me in Arizona. My skin felt fine afterwards, no weird reactions or anything. I'd probably get another one.

I saw some glowing bath bombs on another site, what makes these Bath Diamond ones different than say, Lush or something?

C Cleo Patel 2 months ago
The bioluminescence is the big thing. Lush has cool colors and glitter, but Bath Diamond actually glows like a real bio bay. It's a totally different vibe.

G Greg D. 2 months ago
It's the actual bioluminescence that sets them apart. Other brands might have 'glow in the dark' but this is like, a natural light effect from what I understand, super unique.

Hey, I'm thinking of getting some of these bioluminescent bath bombs for my girlfriend. How long does that glowy effect actually last in the tub?

T Todd Vargas 2 months ago
From what I remember, it's pretty good, like the whole bath. Maybe 20-30 mins? Definitely not super quick fading.

T Troy Vargas 2 months ago
Yeah, it sticks around. I've had a solid 45 minutes of glow from mine before it started to dim. Super cool experience.

How long does shipping usually take? I live in California and wanna get a bundle for a birthday next week.

P Priya 2 months ago
For California, I'd say maybe 5-7 business days, give or take. You might be cutting it close for next week.

I'm on the East Coast and it was about a week for me. With a birthday coming up, you might want to factor in a few extra days just in case.

Any current active discount codes floating around? I'm signing up for the newsletter, but wondered if there's anything else.

C Cleo 2 months ago
Signing up for the newsletter usually gets you a first-order discount code. That's usually the best one unless it's a big holiday.

They often have bundle deals that give you better value than a straight discount code. Keep an eye out for those too.

Anyone know if these are safe for people with sensitive skin? My skin reacts to pretty much everything.

T Tom Torres 2 months ago
I have pretty sensitive skin too and haven't had any issues with their stuff. They use natural ingredients, which probably helps.

D Dana 2 months ago
They say their ingredients are natural and gentle, so I think they're formulated for sensitive skin. Never had a breakout from them.

Does Bath Diamond do free shipping for smaller orders, or do I have to hit a certain amount?

J June Marsh 1 month ago
Pretty sure it's free shipping if your order is over 50 bucks. Anything less and you'll probably pay for it.

S Steve L. 1 month ago
Yeah, it's over $50 for free shipping. If you're getting a bundle, you'll probably hit it easily.

Are their bath bombs difficult to return if I change my mind? Never returned bath stuff before.

J Jared Torres 1 month ago
Nah, returns were pretty straightforward for me. Just followed the instructions on their site.

I had to return a gift set once and it was super easy. No hassle at all. Just make sure it's within their return window.

Will these glowing bath bombs stain my white bathtub? That's the only thing holding me back.

S Sarah Okafor 2 months ago
I've never had any staining issues with them. They dissolve clean and the tub is fine afterward.

R Ryan 2 months ago
Nope, didn't stain my tub at all. The glow is from the ingredients, not dye that sticks. You're good.
